Garmin Fenix Strap Size Guide (All Models Explained)

Choosing the correct Garmin Fenix strap size is essential for comfort, performance and security, especially if you train, race or wear your watch all day.

This guide breaks down every Garmin Fenix strap size, explains the difference between attachment systems, and helps you confidently choose the right replacement strap for your exact model.

How Garmin Fenix Strap Sizes Work

Garmin Fenix watches use a fixed lug width, measured in millimetres (mm). This measurement determines which strap will fit your watch correctly.

If the strap width does not match your watch:

• The strap will not attach securely

• The watch may move during activity

• Sensors may lose consistent skin contact

That’s why strap size matters just as much as material or style.

Do Garmin Fenix Watches Use QuickFit or Quick Release?

All Garmin Fenix models use QuickFit-style straps, not standard quick release.

Key differences:

• QuickFit-style straps clip directly into the watch with no tools required

• Quick Release straps use a small spring bar and lever and are found on lighter Garmin models, not Fenix. The pin is on the strap when unattached. 

If you own a Fenix, you must choose a strap designed specifically for Garmin QuickFit compatibility.

How to Check Your Garmin Fenix Strap Size

If you’re unsure which model you have, you can confirm your strap size in a few simple ways:

1. Check the back of the watch

Many Garmin watches list the strap width on the case back.

2. Check the inside of your current strap

Original straps often have the size printed on the inside.

3. Measure the lug width

Remove the strap and measure the distance between the lugs using a ruler or caliper. The measurement in millimetres is your strap size.

Choosing the Right Strap for Your Garmin Fenix

Once you know your strap size, the next step is choosing the right material.

Popular options:

• Silicone Fenix straps – Ideal for training, running, gym and everyday wear

• Nylon Garmin Straps or fabric straps – Lightweight, breathable and comfortable for long sessions

• Leather Garmin straps – Smart, casual styling for non-training use

• Metal straps – Durable with a premium look and feel

As long as the width matches your watch, the strap will fit correctly.
