How to Fold a Flag for a Display Case: Step-by-Step Guide (2026)
To fold a flag for a display case, hold it waist-high with a partner, fold in half lengthwise twice with stripes inside, then make 13 triangular folds from the striped end toward the blue field — the finished triangle shows only the stars. Without the correct fold sequence, the flag won’t fit the case and the presentation dishonors its significance. This guide covers the exact 13-fold method, funeral flag protocol, case sizing by flag dimension, and which display cases protect the flag long-term.

Quick Answer
Fold a flag for a display case by folding it in half lengthwise twice (stripes inside), then make 13 triangular folds from the striped end toward the blue field. Tuck remaining fabric into the pocket. The finished triangle shows only the blue field with stars — the standard military presentation fold.
How to Fold a US Flag for a Display Case
The American flag fold used for display cases is the same 13-triangle fold performed at military funerals. Each of the 13 folds represents something — the original colonies, valor, honor, and remembrance. The finished triangle should fit neatly into a standard shadow box, with only the blue field (stars) visible from the front. The same wood finishing techniques used for furniture apply when staining a DIY display case to complement the folded flag.
Step-by-Step Flag Folding Guide
| Step | Action | Notes |
|---|---|---|
| 1 | Hold flag waist-high, parallel to ground | Two people required; keep taut |
| 2 | Fold in half lengthwise | Stripes inside, union (blue) on top |
| 3 | Fold in half lengthwise again | Blue field on the outside now |
| 4 | Begin triangular folds from striped end | Fold bottom corner up to top edge |
| 5–15 | Continue triangular folds toward blue end | Make 13 total folds |
| 16 | Tuck remaining fabric into the pocket | Blue field with stars faces up |
| 17 | Place in display case stars facing out | Triangle points right in standard cases |
Flag Folding Materials You Need
Flag: Get a clean and dry flag in good condition — not torn or dirty. The flag should be wrinkle-free before folding. Iron on low heat with a press cloth if needed, then let it cool before folding.
Display Case: Choose a case sized to your flag. A standard 3×5 ft flag folds to roughly 9×9 inches; a military 5×9.5 ft flag folds to about 13×13 inches. See the sizing table below.
Flat Surface: Use a clean table or floor — smooth and clear of objects. A hard surface gives you control over each fold and keeps the flag taut.
Preparing the Flag: Lay Flat and Remove Wrinkles
Place the flag on a clean, flat surface. Spread it fully and smooth out any wrinkles with your hands before making the first fold. Creases set during lengthwise folding will be visible in the final triangle, so this step matters. For nylon and polyester flags, a low-heat iron with a press cloth removes stubborn creases. Cotton flags tolerate slightly more heat.
Fold in Half Lengthwise (First Fold)
Hold the flag by opposite corners, lengthwise, waist-high between two people. Fold the lower half up so the stripes are on top of the blue field. Align the edges carefully — all edges must be even. A misaligned first fold throws off every subsequent triangular fold, so take time here to get it straight.
Fold in Half Lengthwise Again (Second Fold)
Fold the flag lengthwise a second time. After this fold, the blue field (union) should be on the outside. Press along the fold to keep it flat. Check the edges — they should align perfectly. A smooth second fold sets up clean triangular folds in the next steps.
Begin the 13 Triangular Folds
Start at the striped end (opposite the blue field). Fold the lower right corner diagonally up to meet the top edge of the flag, forming a triangle. Then fold the triangle forward along the top edge again. Each fold should form a right angle. Keep every fold tight — a loose fold means the flag won’t fit the display case and will lose its shape. Continue making triangular folds — there are 13 total — until you reach the blue field end.
Tuck Remaining Fabric and Place in Case
After all 13 folds, tuck any remaining fabric into the open pocket of the triangle. Secure it with gentle pressure — snug, not strained. The finished triangle shows only the blue field with stars facing up. Place in your display case with stars facing outward through the glass. The triangle typically points right in standard cases.
How to Fold a Funeral Flag for a Display Case
A funeral flag — also called a burial flag — is folded identically to a ceremonial display flag. The difference is context: at a military funeral, the flag is folded by two service members and presented to the next of kin with the words “on behalf of the President of the United States.” The fold itself is the same 13-triangle technique.
If you received a burial flag and want to preserve it, make sure the case is at least 12×12 inches wide for a standard 5×9.5 ft flag. Many families use a shadow box deep enough to add a photo, medals, or a nameplate alongside the folded flag. When finishing a DIY display case, choose danish oil or polyurethane depending on the sheen and protection level you want. For wall mounting the display, the same principles used when building shelves between wall studs apply — find studs and use appropriate anchors for the case weight.
| Flag Size | Folded Triangle Size | Recommended Case Size |
|---|---|---|
| 3×5 ft (standard) | ~9×9 inches | 12×12 in shadow box |
| 4×6 ft | ~11×11 inches | 13×13 in shadow box |
| 5×9.5 ft (military/burial) | ~13×13 inches | 16×16 in shadow box |

Frequently Asked Questions
How do you fold a US flag for a display case?
Hold the flag waist-high with two people, fold in half lengthwise twice (stripes inside), then make 13 triangular folds from the striped end toward the blue field. Tuck remaining fabric into the pocket. The result is a triangle showing only the blue field with stars — the standard military presentation fold.
How many folds does it take to fold a flag for a display case?
It takes 13 triangular folds to fold a flag for a display case, preceded by 2 lengthwise folds. The 13 triangular folds represent the original 13 colonies. After all folds, the remaining fabric is tucked into a pocket to secure the triangle shape.
What size display case do I need for a burial flag?
A standard military burial flag (5×9.5 ft) folds into a triangle approximately 13×13 inches and requires a display case at least 16×16 inches. A standard 3×5 ft flag folds to about 9×9 inches and fits in a 12×12 inch shadow box.
Should you iron a flag before putting it in a display case?
You can iron a nylon or polyester flag on a low heat setting before folding, using a press cloth to protect the fabric. Cotton flags can tolerate slightly higher heat. Never iron a flag with creases from previous folds — iron it flat first, let it cool, then fold. Some veterans organizations advise against ironing burial flags to preserve their ceremonial state.
Can you put a flag in a box without folding it?
Yes — some shadow boxes and display cases hold an unfolded flag mounted flat behind glass. These flag display frames hold a 3×5 ft flag fully extended, requiring a frame approximately 20×38 inches. They show the full flag design but require significantly more wall space than a triangle case.
