Leather Archery Arm Guard Template: Step-by-Step Cutting and Fitting Guide

Updated November 2026

A leather archery arm guard template is a flat pattern you trace onto leather, cut out and shape so it protects your forearm from bowstring slap. With a good template, measurements taken from your own arm, and a few basic tools, you can make a guard that fits snugly, stays in place during a full draw and lasts for years. This guide walks through taking measurements, building the pattern, cutting and fitting the leather, and finishing the edges.

What You Need Before You Start

Gather your materials before you measure. Most of the work is simple, but accurate tools make a visible difference in how the guard sits.

• Vegetable-tanned leather, roughly 2 to 3 mm (about 3/32 to 1/8 inch) thick. Thinner leather tears at the eyelets, and thicker leather is stiff and hard to bend around the wrist.
• A flexible measuring tape and a ruler or straightedge
• Heavy paper or cardstock for the template
• A pencil, awl or stitching chisel
• A sharp utility knife or leather shears, plus a cutting mat
• Hole punch or diamond-tipped awl for eyelet holes
• Waxed linen or nylon thread and two blunt harness needles (for lacing)
• Edge beveler, sandpaper (320 to 400 grit) and leather conditioner

Step 1: Take Accurate Measurements

Your measurements determine every other step, so take them carefully, ideally with a helper. Stand with your bow arm relaxed and slightly bent, as you would hold it at full draw. Record these figures in inches or centimeters and keep them consistent.

1. Wrist circumference: Measure around the wrist bone, just above the joint.
2. Forearm circumference: Measure around the widest part of the forearm, about 4 to 5 inches (10 to 13 cm) up from the wrist.
3. Guard length: Measure from the base of the wrist (a little past the knuckle line) to the point on the forearm where the guard should end, usually around the elbow crease or a little below it. Most target archers end the guard 2 to 3 inches (5 to 8 cm) below the elbow.
4. Wrist-to-bow-side distance: Hold your arm at full draw position and measure the distance from the outside of your wrist to the inside of the forearm where the string travels. This tells you how wide the guard needs to be across the back of the arm.

Add 1/4 inch (about 6 mm) of ease to your circumference measurements so the guard isn’t so tight that it restricts blood flow or wrist movement.

Step 2: Build the Template

A template is a flat paper version of the finished guard. Start with a rectangle that matches your guard length and the width needed to wrap around your forearm. For a single-strap design, the paper should be roughly the forearm circumference plus overlap for the lacing.

Shape the Ends

Round the top (the end nearest the elbow) into a gentle curve so it doesn’t dig into the crease when you bend your arm. Round the bottom corners slightly too. Sharp corners catch on clothing and wear faster.

Mark Lacing Holes

Place lacing holes along both long edges, spaced about 1 inch (2.5 cm) apart and set 1/2 inch (13 mm) in from the edge. Start and end the row about 1 inch from each end. Use the same pattern on both sides so the lacing tension is even.

Test the Fit on Paper

Wrap the paper template around your forearm, overlapping as the finished guard would, and check that it sits without bunching. Mark any spots that feel tight or loose, then adjust. This step saves leather, which is far more expensive than paper.

Step 3: Transfer and Cut the Leather

1. Lay the template on the leather’s smooth grain side (the outer surface) and trace around it with a pencil or awl.
2. Transfer the lacing hole marks by pressing the awl through the paper into the leather, or punch them with a hole punch sized for your lacing.
3. Cut along the traced line with a sharp utility knife, using a straightedge for straight sections. Make several light passes rather than one hard cut, which keeps the edge clean.
4. Check the blank against your forearm before going further.

Step 4: Shape and Pre-Form the Leather

Dampen the leather lightly with water or a damp cloth and let it rest for 10 to 15 minutes until it becomes pliable but not soaking wet. Wrap it gently around your forearm or a cylindrical form, such as a rolled towel or a piece of PVC pipe of similar diameter. Let it dry in that shape overnight. Pre-forming reduces the tendency of the guard to flatten or twist once worn.

Step 5: Finish the Edges

Bevel the cut edges with an edge beveler, then sand them smooth with 320 to 400 grit paper. Rounded edges resist fraying and won’t scratch your skin. Finish with a light coat of leather conditioner, then let it dry fully before lacing.

Step 6: Lace and Adjust the Guard

Thread the waxed cord through the holes in a criss-cross pattern, tying it off at one end. Tighten gradually from the center outward, and make sure the cord doesn’t pinch the skin. The guard should sit snug but not tight, with about one finger’s width of space between the leather and your arm when your bow arm is relaxed. Test by drawing and releasing a few arrows, then re-tighten or loosen as needed.

Common Mistakes to Avoid

• Cutting before testing the paper template. Always check fit on paper first.
• Using leather that is too thick. Heavy leather resists bending and can cause pressure points.
• Skipping the pre-form step. Unshaped leather tends to flatten and roll.
• Lacing too tightly. Tight laces reduce circulation and make the guard uncomfortable during long sessions.
• Placing the top edge too high. A guard that presses into the elbow crease limits bending and can feel restrictive at full draw.
• Rough or unfinished edges. These fray, catch on clothing and scratch skin.

Tips for Better Results

• Make a second paper template at a slightly different width and test both before committing to leather.
• Keep a finished guard as a reference for future projects, noting the measurements you used.
• Use a scrap piece of leather for a practice cut to learn how your knife behaves on the grain.
• If your bow string tends to hit one spot of your arm, you can add a small extra layer of leather in that area rather than making the whole guard thicker.
• Store finished guards flat or lightly rolled, away from heat, so the leather keeps its shape.

Recommended gear

Sharp cutting tools make the biggest difference in clean leather work. A rotary or utility knife with replaceable blades is a practical choice, and a cutting mat protects your work surface. A diamond-tipped awl or a hole punch sized for your lacing cord keeps eyelet holes consistent. Edge beveling is easier with a dedicated edge tool, and a leather conditioner keeps the finished guard supple.

FAQ

What thickness of leather works best for an arm guard?

Most makers use vegetable-tanned leather between 2 and 3 mm thick. It holds its shape, bends around the forearm and resists tearing at the lacing holes.

How long should a leather arm guard be?

Length depends on your arm and how much coverage you want. Many target archers end the guard 2 to 3 inches below the elbow, but you should test the fit with the paper template first.

Can I make a template without measuring my arm?

You can use a commercial pattern, but measured templates fit better. Measuring your wrist, forearm and guard length takes only a few minutes and greatly improves comfort.

Should I dampen the leather before shaping it?

Yes, a light dampening makes vegetable-tanned leather easier to shape. Let it dry in the formed position so it keeps its curve.

How tight should the laces be?

The guard should sit snugly without pinching. You should be able to slide a finger between the leather and your arm when your bow arm is relaxed.

How do I stop the guard from shifting during a shot?

Pre-forming the leather to your arm’s curve and lacing evenly usually prevents movement. If it still shifts, check that the top edge isn’t too high and that the lacing is balanced on both sides.

How often should I replace a leather arm guard?

Replace it when the lacing tears through the holes, the leather cracks or the guard no longer holds its shape. Regular conditioning slows wear.

Conclusion

A leather archery arm guard template turns a simple pattern into a guard that fits your arm. Measure carefully, test on paper, cut and pre-form the leather, then finish and lace with care. Taking your time at the template stage pays off with a guard that protects you well and stays comfortable through long practice sessions.
