Hardwood Species Hardness Chart: Janka Rating By Floor Type
For hardwood floors, many people treat around 1,200 as a practical starting point for main living areas, around 1,500 or more for busier homes, and under 1,000 mainly for lower-traffic rooms. Choose too soft a species and you’ll see dents from chair legs, pet nails, dropped pans, and high heels much sooner. This guide compares common species by Janka rating and turns those numbers into room-by-room picks for solid and engineered hardwood.
How should homeowners use a Janka chart when choosing flooring?
A Janka chart works best as a filter, not a final answer. It narrows the field by dent resistance, then room use, impact risk, and maintenance habits decide the rest. A raw species list misses the difference between a quiet bedroom, a gritty entryway, and a kitchen with stools, pans, pets, and daily spills.
Why a species chart alone leaves out the real decision
Most charts tell readers that one species is harder than another, then stop. That helps, but it is incomplete. Flooring succeeds or fails by room conditions.
An entryway gets sand, pebbles, wet shoes, and hard heel strikes. A bedroom gets socks, soft slippers, and lighter furniture movement. I have seen the same wood look tough in one room and tired fast in the next.
The three inputs that matter most
Homeowners get better flooring choices by weighing three things together:
- Traffic volume: how many passes the floor sees each day.
- Impact load: pet nails, chair legs, stools, dropped cookware, and heels.
- Maintenance habits: mats at doors, felt pads, chair protectors, grit control, and finish upkeep.
That mix matters more than a species rank by itself. A medium-hard floor with strict grit control often stays cleaner-looking than a harder floor abused at the door.
How this guide converts hardness numbers into room choices
The practical use of Janka is simple: compare a wood against known flooring benchmarks, then place it into a room band. Red oak and white oak are useful reference points because many buyers already know them, and many flooring discussions use them as familiar baselines.

What does the Janka hardness test actually measure?
The Janka hardness test measures how much force it takes to press an 11.28 mm steel ball into wood until the ball is buried to half its diameter. In flooring terms, that gives you a side-by-side denting comparison, the kind of damage you see from chair legs, heel points, and dropped objects. That is why Janka ratings are widely used for flooring comparisons.
How the steel ball test works
The method is straightforward. Janka uses an 11.28 mm steel ball, and the test presses that ball into the sample until the ball is embedded to half its diameter.
The force required for that embedment becomes the rating. Higher force means better resistance to denting under that test setup.
What the force number tells you
The number is best read as a dent-resistance comparison. If one species rates far above another, it usually stands up better to concentrated pressure from furniture legs, heel points, toy impacts, and similar loads.
That makes Janka useful for flooring. It does not make it complete.
What Janka does not measure
Janka does not measure scratch resistance, finish wear, water resistance, seasonal movement, or long-board stability. It also does not tell you how a floor will look after years of dog traffic or rolling office chairs.
That distinction matters because readers often confuse scratch marks with dents. I run into this all the time. A floor can resist indentation well and still look rough if the finish scratches easily, the sheen is glossy, or the room tracks in grit every day.
What Janka rating is durable enough for hardwood floors?
For most homes, a practical flooring range starts around Janka 1,200 for everyday living areas, moves into a safer busy-home zone around 1,500 and above, and gets risky below 1,000 outside lower-wear rooms. There is no single magic cutoff because stairs, kitchens, bedrooms, and rentals take very different kinds of abuse.
Lower band: under 1,000
This is where caution starts for active households. Softer species can still work, especially in bedrooms, formal sitting rooms, and homes with careful maintenance, but they show chair-leg dents and impact marks sooner.
Cherry sits in this softer group and is a good example of a species many people love visually but should place with care.
Middle band: about 1,000 to 1,499
This is the everyday flooring range. It covers familiar species that work well in living rooms, many kitchens, and general household use when paired with decent finish choices and basic floor protection.
Red oak and white oak live here and make good benchmarks because they balance dent resistance, availability, and livability.
Upper band: 1,500 and up
This is where busy entries, active homes with kids, larger dogs, stairs, and light commercial use start to make more sense. Hard maple and beech are useful comparison species here.
Even here, hardness does not make a floor damage-proof. I have seen grit scratch tough floors, heavy dropped objects bruise edges, and rolling loads leave wear paths long before the wood itself looked weak.
Hardwood species hardness chart: Janka ratings and flooring guidance
How to read the table
The table below pairs commonly cited Janka comparison values with practical flooring guidance. Species ratings can vary slightly by source, growing conditions, and sample cut, so the best comparisons come from using one chart consistently rather than mixing values from several places.
| Species | Typical Janka rating | Dent-resistance rank | Traffic-use guidance | Best floor-type fit |
|---|---|---|---|---|
| Cherry | 950 | Soft among common hardwood floors | Low to moderate traffic | Bedrooms, lower-wear living spaces |
| Walnut | 1010 | Moderate | Moderate traffic | Bedrooms, living rooms, offices without rolling chairs |
| Red oak | 1290 | Mid-high benchmark | Moderate to busy residential use | Living rooms, halls, many kitchens |
| White oak | 1360 | Mid-high benchmark | Moderate to busy residential use | Living rooms, kitchens, hallways, many stairs |
| Beech | 1300 | Mid-high | Moderate to busy residential use | General living areas, stairs with good finish maintenance |
| Hard maple | 1450 | High for common North American flooring woods | Busy residential to light commercial | Entries, kitchens, stairs, active homes |
Benchmark species: red oak and white oak
Ocooch Hardwoods lists Red Oak among stocked species and lists White Oak among stocked species. Those two are practical reference woods because they sit in a useful middle-to-upper residential range without drifting into extremes.
Red oak is the common benchmark. White oak pushes a little harder while also being a frequent choice where buyers want a more durable-feeling floor under daily use.
Harder options: hard maple and beech
Ocooch Hardwoods lists Hard Maple among stocked species. Among common North American flooring woods, hard maple is usually one of the harder choices people compare when dent resistance matters.
Beech belongs in the same discussion because it offers a similar use case on paper: good dent resistance for busy homes. Still, neither species gets a free pass on surface scratching or finish wear.
Softer to moderate options: walnut and cherry
Ocooch Hardwoods lists Walnut among stocked species and lists Cherry among stocked species. Both are real flooring options, but each needs smarter room placement than oak or hard maple.
Walnut is moderate. Cherry is softer than maple and oak. That does not make them bad floors. It makes them better fits for rooms with lower impact and better habits.
How do oak, maple, walnut, cherry, and beech compare in real homes?
In real houses, red oak and white oak are the baseline performers, hard maple is the harder step up for busier wear, beech sits near the oak range, walnut is more mark-prone, and cherry belongs in gentler rooms. The best choice depends less on the chart alone than on pets, heels, chairs, and grit control.
Red oak vs white oak as baseline flooring choices
Red oak is the reference point many homeowners can understand immediately. If a species falls below red oak, expect greater dent risk. If it lands above white oak, it starts to look more appealing for active use.
White oak adds a little more dent resistance and is often the safer baseline for kitchens, halls, and busier family rooms.
Where hard maple earns its reputation and where it can still disappoint
Hard maple earns attention because it is typically among the hardest North American flooring woods used for interior applications. In homes with dogs, kids, or rental turnover, that extra margin can matter.
Still, hard maple can disappoint when buyers assume hard means scratch-proof. Pet nails, grit, and a shiny finish can leave visible lines on a hard maple floor just as surely as on a softer one.
Why walnut and cherry suit some rooms better than others
Walnut works well where people want a warmer, darker look and can accept more visible wear over time. It is more prone to dents than oak and maple, so busy kitchens and entries are a gamble.
Cherry is softer again. It makes more sense in bedrooms, studies, and lower-wear rooms where dropped objects and point loads are less frequent.
When beech belongs in the discussion
Beech is often skipped in basic charts, but it is a useful comparison reference. On hardness, it runs close to the stronger everyday flooring group, so it deserves consideration when oak and maple are being weighed.
Room-use matrix: which Janka bands are safe, caution, or avoid by floor type
Original room-use matrix
This matrix turns Janka bands into room decisions. “Safe” means the hardness level generally fits the room if the finish and maintenance are sensible. “Caution” means it can work, but expect visible wear sooner or plan stronger protection. “Avoid” means the dent risk is high for normal use.
| Janka band | Entryway | Kitchen | Living room | Bedroom | Stairs | Commercial-light-use |
|---|---|---|---|---|---|---|
| Under 1,000 | Avoid | Avoid | Caution | Safe | Avoid | Avoid |
| 1,000 to 1,199 | Caution | Caution | Safe | Safe | Caution | Avoid |
| 1,200 to 1,499 | Safe | Safe | Safe | Safe | Safe | Caution |
| 1,500 and up | Safe | Safe | Safe | Safe | Safe | Safe |
How to use the matrix room by room
Entryways punish floors with grit and heel strikes, so softer species move into avoid territory fast. Kitchens get repeated point impacts from stools, cookware, and standing traffic. Stairs compress wear into a smaller footprint, which is why marginal species often look tired there first.
Bedrooms are the forgiving room. That is where cherry and walnut make the most sense for buyers who love their look and can accept a little wear history.
Is a higher Janka rating always better for flooring?
A higher Janka rating is better when the floor faces repeated dents, heavy point loads, pets, or hard daily traffic, but it is not automatically the best flooring choice. Very hard woods can still scratch, can feel harsher underfoot, and can bring tradeoffs in milling, edge behavior, and how forgiving the floor feels in lived-in spaces.
The upside of harder species
Harder woods buy time. Chair legs leave fewer bruises. Stilettos do less damage. Stair nosings and hallways hold up better under repeated concentrated pressure.
That is why hard maple keeps coming up in active-home discussions.
The downside of chasing the highest number
Hardness alone can lead buyers astray. Very hard flooring can still chip on sharp impacts, splinter at edges, or show finish damage before the wood itself dents.
It can also be less forgiving during installation and later repair. Boards that resist indentation well may still show ugly surface wear if the finish choice is poor.
Why a balanced floor often wins
A balanced floor is one that matches hardness to room use, finish to lifestyle, and appearance to expected wear. For many homes, white oak or red oak is a smarter all-around choice than chasing the hardest species available.
What matters besides hardness when floors get scratched, dented, or worn?
Hardness is only one piece of floor performance. Visible wear comes from three separate issues: dents in the wood, scratches in the wood or finish, and finish erosion from repeated traffic. Pets, heels, rolling chairs, grit, board cut, color, and sheen often change what owners actually notice more than a moderate shift in Janka score.
Dent resistance vs scratch visibility vs finish wear
Dents are compression damage. Janka helps here. Scratches are surface cuts or abrasions. Finish wear is the loss or dulling of the protective coating.
These are related, but different. A floor can resist dents well and still look rough because a glossy finish makes every scratch stand out.
Pets, heels, dropped objects, and rolling chairs
Dog nails rarely act like the Janka ball. They create repeated tiny contacts and carry grit. High heels concentrate force into a very small point. Rolling office chairs add motion and grit. Dropped pans hit with sharp impact.
Those failure cases are why hardness charts need real-room context. A hard species without door mats and chair protection still ages fast.
Board cut, grain, color, and sheen
Grain pattern changes what wear looks like. Busy grain can hide light marks better than a plain, uniform surface. Dark floors often reveal pale scratches. High sheen makes every defect easier to see.
That is why visible wear and actual wear are not the same thing.
Why grit at the door beats hard wood
Sand is brutal. It rides under shoes, paws, and chair feet, and it acts like abrasive paper on the finish. A harder species does not stop that. Good mats, frequent sweeping, and quick grit removal do more for appearance than many buyers expect.
Does engineered vs solid hardwood change the hardness decision?
Engineered vs solid changes the installation and moisture side of the decision more than the Janka number itself, because the top wear layer species still drives dent resistance. Engineered flooring can be a smart choice in kitchens or mixed conditions, but wear-layer thickness and refinishing limits matter before hardness alone settles the purchase.
Why the top veneer species still controls Janka performance
If the face layer is white oak, the floor behaves like white oak at the surface. If the face layer is walnut, it will show walnut-like denting at the surface. Core construction does not turn a softer species into a hard one.
When engineered hardwood makes sense
Engineered flooring makes sense where moisture swings or subfloor conditions make solid wood less practical. Kitchens, lower levels, and wide-plank layouts often push buyers in that direction.
That does not change the need to choose the right species for the room. A soft face veneer in a rough-use kitchen is still a soft face veneer.
Wear layer limits and refinishing tradeoffs
When hardness is the deciding factor, buyers should also ask how much wear layer exists above the core. A species that marks more easily may still be acceptable if future refinishing is realistic. Thin wear layers give less margin for fixing dents and traffic wear later.
What is the difference between hardwood and softwood?
Hardwood is wood from flowering angiosperm trees, while softwood comes from gymnosperm trees. That botanical difference does not mean every hardwood is hard in floor use. Some hardwoods are softer than most softwoods, so species-by-species comparison matters more than the label alone.
Why the names confuse buyers
Hardwood sounds like a promise. It is not. Hardwood and softwood are tree groups first. Flooring performance still varies widely inside each group.
That is why a hardwood floor can still dent more easily than buyers expect.
Frequently asked questions
What is the Janka hardness rating for different hardwood flooring species?
Common comparison values place cherry around 950, walnut around 1010, red oak around 1290, beech around 1300, white oak around 1360, and hard maple around 1450. Use those numbers as a side-by-side dent-resistance guide, while remembering that ratings can vary slightly by source and sample.
Which hardwood species are best for high-traffic floors?
For busy residential floors, hard maple, white oak, beech, and red oak are the stronger mainstream picks in this group. Hard maple usually offers the most dent resistance here, while white oak and red oak remain balanced choices for rooms that need durability without overthinking the species decision.
Is a higher Janka rating always better for flooring?
No. Higher Janka helps with dent resistance, but it does nothing by itself for scratch resistance, finish life, water resistance, or movement control. A very hard species with a glossy finish in a gritty entry can look worse over time than a slightly softer species placed in the right room.
What Janka rating is considered durable enough for hardwood floors?
A practical guide is about 1,200 for main living areas, about 1,500 and up for busier homes with dogs or kids, and under 1,000 mainly for lower-traffic rooms. That is a room-based threshold, not a universal rule, because stairs and entryways punish floors far harder than bedrooms.
How do oak, maple, walnut, and cherry compare on hardness?
Hard maple sits highest among these common choices, white oak and red oak form the everyday benchmark middle, walnut is lower and more prone to dents, and cherry is softer still. In room planning terms, oak and maple suit busier areas better, while walnut and cherry fit calmer rooms.
Does Janka hardness measure scratch resistance or dent resistance?
Janka measures dent resistance. The test uses an 11.28 mm steel ball embedded to half its diameter, and the resulting force value compares how much the wood resists indentation from concentrated loads such as chair legs and heels. It does not measure scratch resistance, finish durability, moisture behavior, or overall floor longevity.
