Glue Gun Stick Sizes: Mini vs Full-Size Diameter Chart

Hot glue sticks come in two common diameters: full-size at 0.43 inches (11mm) and mini at 0.27 inches (7mm), and your gun accepts only one of them. Length is a separate spec, so a 4-inch stick is not automatically mini. This guide gives the full size chart in inches and mm, a pack-price comparison by inches of glue, and how woodworkers use full-size sticks on jigs.

Glue Gun Stick Sizes at a Glance

Diameter is the number that matters. Length only changes how often you reload.

Size	Diameter (in)	Diameter (mm)	Common lengths	Fits
Mini	0.27 to 0.28	about 7	4 in; also sold in 10 in	Compact craft guns
Full-size	0.43 to 0.44 (7/16)	about 11	4 in or 10 in	Standard, high-temp and dual-temp full-size guns

Both 4-inch and 10-inch full-size packs exist: one listing we checked sells 0.43-inch sticks in a 4-inch length, while the AdTech pack above is 10 inches long. Mini sticks are also sold in 10-inch lengths, so always check the diameter and not just the length.

Common Glue Stick Sizes: Standard vs Mini

Standard (Full-Size) Sticks

Full-size sticks are the default for hardware-store guns. The nominal size is 7/16 inch, which is 0.4375 inches or about 11.1mm; most packs print 0.43 or 0.44 inches. They feed through a wider chamber and deliver more glue per trigger pull, which is why they suit gap-filling and larger surfaces.

Mini Sticks

Mini sticks are about 7mm (0.27 to 0.28 inches). They fit compact guns built for detail work. Surebonder, a stick manufacturer, describes mini guns as made for precise control on small, detailed tasks. Bond strength is not the difference here: temperature rating and formula decide that, which we cover in our guide to different hot glue stick strengths.

Understanding Size Labels

Labels such as full-size, standard, jumbo and mini are not regulated, so one brand’s jumbo can be another brand’s standard. Ignore the label and read the diameter in mm or inches. Low-temp and high-temp are a separate property again: a full-size stick can be either, so see our hot glue stick types by temperature and material for that choice.

Matching Glue Sticks To Your Glue Gun

Compatibility Issues

Each gun’s feed chamber and drive are built for one diameter. According to Surebonder, using the wrong size could cause jams or backflow. A full-size stick is about 4mm thicker than a mini stick, so it will not enter a mini gun at all; do not shave, crush or force it. A mini stick in a full-size gun is the loose-fit case and can slip past the feed or leak back out of the rear.

How To Measure Your Stick

• Calipers: read about 10.9 to 11.2mm for full-size, about 6.8 to 7.1mm for mini.
• Drill bit gauge: a 7/16 inch bit (0.4375 inches) is a close match for a full-size stick, and a 9/32 inch bit (0.281 inches) for a mini stick.
• Package: look for the diameter in mm or inches, then confirm it against your gun’s manual or the markings near the feed port.

Hot Glue Sticks for Woodworking Jigs and Temporary Fixtures

Hot glue is a genuine shop tool, not just a craft-table item. Woodworkers reach for full-size sticks when they want a fast, removable hold instead of a permanent wood-glue joint. Common uses:

• Stop blocks and fences: tack a stop block to a miter saw fence instead of clamping it, then pop it free with a chisel when the cut run is done.
• Sacrificial clamping blocks: glue a small or oddly shaped workpiece to a larger scrap so you have something to clamp, then release it afterwards.
• Planer sled shims: tack thin shims under a rough board on a planer sled to hold it steady.
• Batch jig assembly: tack parts to a template for repeat cuts, then peel them off between pieces.

Full-size sticks are the better choice here because they deposit more adhesive per pull. Hot glue does bond to wood, but it will not hold structural weight. Treat it as a setup and alignment aid, never as a joint that carries load. For a head-to-head on when each adhesive wins, see hot glue vs wood glue for quick fixes.

Price Per Stick and Per Inch: Pack Size Math

Pack price alone misleads because a 4-inch stick holds 40 percent as much glue as a 10-inch stick. Dividing the price by total inches of glue gives a fairer number. Prices below are current Amazon listing prices as of October 5, 2026 and will change:

Pack	Stick length	Price	Per stick	Per inch of glue
AdTech 85-pack	10 in	$18.59	about $0.22	about $0.022
YesBes 100-pack	10 in	$26.99	about $0.27	about $0.027
Surebonder 50-pack	4 in	$6.88	about $0.14	about $0.034
AdTech 24-pack	10 in	$8.47	about $0.35	about $0.035

The cheapest pack per stick is not the cheapest per inch: the 4-inch Surebonder looks like a bargain at 14 cents but costs about the same per inch as the 24-pack of 10-inch sticks. The 85-pack is the best value per inch of the four, and the 24-pack is the better choice if you only want to try full-size sticks first.

Where To Buy

Hardware stores, craft stores and big-box retailers stock both sizes, usually in small blister packs that cost more per inch than bulk cartons. Our guide to hot glue guns at Lowe’s covers wattage and stick sizes for the guns sold there. For more adhesives, browse the glue category.

Which Size Should You Buy?

• Your gun is full-size and you work with wood: buy 10-inch full-size multi-temp sticks in a large pack. You reload less often and pay less per inch.
• Your gun is a compact mini model: buy mini sticks only, and check the package for the 7mm diameter. A full-size pack will not fit, no matter how cheap it is.
• You are not sure what your gun takes: measure the feed opening or an old stick with calipers before ordering a multi-pack, or buy a small pack first.
• You want to avoid a refund hassle: confirm the diameter in the product title or bullet points, since the label alone (jumbo, standard, regular) is not a reliable size.

The most common mistake is buying by length alone. A 10-inch stick can be either diameter, so a long stick in your cart does not guarantee it fits the gun on your bench.

Usage Tips

• Let the gun heat fully before loading and pulling the trigger; forcing a stick into a cold chamber is a common cause of jams.
• Push the stick in straight and stop pushing when it flows; pressing harder does not increase glue flow.
• Keep sticks in a cool, dry place away from heat, since they can soften and bend.
• Unplug the gun and let it cool before swapping to a different stick size or type.

Frequently Asked Questions

What Are The Glue Stick Sizes?

Hot glue sticks come in two common diameters: mini at about 0.27 inches (7mm) and full-size at about 0.43 inches (11mm). Lengths vary separately, usually 4 inches or 10 inches. Diameter decides whether a stick fits your glue gun, so check it before you buy.

What Two Common Sizes Do Glue Sticks Come In?

The two common sizes are mini (7mm, about 0.27 inches) and full-size (11mm, about 0.43 inches). Length is a separate choice: full-size sticks are sold in both 4-inch and 10-inch lengths, and mini sticks are sold in 4-inch and longer lengths.

How Do You Know The Size Of A Glue Stick?

Read the diameter on the package, or measure the stick with calipers or a drill bit. A stick that matches a 7/16 inch bit is full-size (11mm); one closer to a 9/32 inch bit is mini (7mm). Do not rely on labels like jumbo, which have no fixed meaning.

Do All Glue Guns Take The Same Size Glue Sticks?

No. Each gun has a feed chamber built for one stick diameter, usually mini (7mm) or full-size (11mm). A full-size stick will not enter a mini gun, and a mini stick in a full-size gun can slip, jam or flow back. Check the gun’s manual.

Can You Use a Hot Glue Gun for Woodworking Jigs?

Yes. Hot glue is a common shop trick for temporary holds, such as tacking stop blocks to a fence or gluing a workpiece to a sacrificial clamping block. Full-size sticks carry more adhesive per pull. It is not a substitute for wood glue on structural joints.

Conclusion

Check the diameter, not the label: full-size is about 11mm (0.43 inches) and mini is about 7mm (0.27 inches), and the two are not interchangeable. Pick length by how often you want to reload, and compare packs per inch of glue instead of per stick. For shop jigs, a full-size multi-temp stick is the practical choice.
