Leather Arm Guard Template: Step-by-Step Guide for Beginners

Updated November 2026

A leather arm guard template is a flat paper or cardboard pattern that shows you exactly where to cut, shape, and place the leather so the guard fits your forearm. Once you have a working template, you can build a guard that protects your wrist from bowstring slap and stays put during a full draw. This guide walks through measuring, drafting, transferring, and fitting the pattern.

Measure Your Forearm and Mark Key Points

Start by measuring your bow arm, not your shooting arm. Wrap a soft tape around the forearm about 2 inches below the elbow to get the circumference, then measure from the wrist crease to the point where the guard should end, usually 3 to 4 inches toward the elbow. Record both numbers, plus the width you want across the back of the arm.

Most archers wear the guard on the inside of the forearm, where the string lands. Stand with your bow arm extended as if at full draw and mark the spot where the string strikes most often, usually with a strip of masking tape.

Draft the Pattern on Paper

Use kraft paper, poster board, or an old file folder. Draw a rectangle equal to your forearm length plus about 1/2 inch of overlap, and as wide as half your forearm circumference plus the same overlap. Round the corners slightly so the edges will not dig in. Then mark a curved line along the inside to follow the natural taper of your arm.

Wrap the paper around your forearm and tape it closed. Check that it sits snug without restricting blood flow or wrist movement. Trim and adjust until the fit is comfortable, then trace the final shape onto clean paper.

Transfer the Template to Leather

Lay the paper pattern on the leather flesh side up, and trace around it with a fine silver pen or awl. Leave room for stitching holes and a belt-loop or strap tab if you plan to use one. Mark the stitch line about 1/4 inch from the edge, then punch holes at even spacing.

1. Trace the outline and mark stitch holes.
2. Cut slowly with a sharp utility knife, using a straight edge for long lines.
3. Skive or thin the edges where they will fold or overlap.
4. Punch stitch holes with a diamond chisel or awl.
5. Dampen the leather lightly and shape it around a forearm mold or a rolled towel.

Fit, Finish, and Test the Guard

Once the guard is stitched and dried, put it on with the strap snug but not tight. Draw your bow slowly several times and check that the guard stays centered over the forearm. If the edge digs into your skin, trim or reshape that section and re-test before final finishing.

Recommended gear

• Leather stitching kit: Pre-punched holes and waxed thread make even stitch lines simpler for a first build. View on Amazon
• Cutting mat and utility knife: A self-healing mat protects your work surface and keeps cuts clean. View on Amazon
• Leather edge slicker: A slicker or burnishing tool smooths cut edges so they will not snag on clothing. View on Amazon

Common Mistakes

• Measuring the wrong arm or measuring with the arm tensed.
• Making the template too tight, which restricts circulation and wrist movement.
• Skipping a test draw before finishing the stitching.
• Placing stitch holes too close to the edge, causing tears under tension.
• Cutting leather without checking that the strap closure reaches your wrist comfortably.

FAQ

What leather thickness works best for an arm guard?

Many archers use leather in the range of 2 to 3 millimeters, which is firm enough to block string slap while staying flexible. Thinner leather can be more comfortable but may wear faster.

Can I make a leather arm guard template without special tools?

Yes. Paper, a pencil, tape, a utility knife, and an awl are enough for a basic pattern and guard. Specialty tools make stitching and finishing cleaner but are not required.

How long should the guard be?

Most guards cover from just below the elbow to about 3 to 4 inches above the wrist crease. Adjust the length based on where your string typically strikes.

Conclusion

A well-made leather arm guard template saves time and gives you a guard that fits your arm rather than a generic size. Measure carefully, draft on paper, and test before finishing. Take your time with the first pattern, and refine it after a few sessions on the range.
