Guitar Strap Hole Size Standard: 8mm. (5/16") & FREE Custom Adapting
Guitar Strap Hole Size Guide
Most guitar straps use a standard 8 mm (5/16") hole, but some strap locks may require 6 mm, 10 mm, or 12 mm for the right fit.
This guide explains the most common guitar strap hole sizes, when you may need a custom diameter, and how to choose between sliced and no-slice leather ends.
Quick answer: The standard guitar strap hole size is 8 mm (5/16"). If you use strap locks, you may need a larger hole, usually 10 mm or 12 mm. At Pardo Guitar Straps, custom hole sizes are available at no extra charge.
Guitar Strap Hole Sizes at a Glance
Visual guide: The diagram below shows how different hole sizes relate to standard buttons and strap lock systems.
The hole size is the diameter of the opening in the leather end of the strap. This is the part that connects to your guitar’s strap button or strap lock system.
- 8 mm (5/16") — standard size for most guitar straps
- 6 mm (≈ 1/4") — for smaller strap buttons or specific hardware
- 10 mm (≈ 3/8") — common for Schaller-style strap locks or similar systems
- 12 mm (≈ 1/2") — for larger strap lock buttons or custom fittings

The Standard Guitar Strap Hole Size
For most guitars, the standard guitar strap hole size is 8 mm (5/16"). This is the most common size used for regular strap buttons.
It is also the standard size we use at Pardo Guitar Straps.
Tip: If your strap fits a regular guitar strap button securely, you probably need the standard 8 mm hole.
When You May Need a Custom Hole Size
The standard 8 mm (5/16") hole does not work for every setup. The right size depends on the strap buttons or strap locks installed on your guitar.
You may need a custom hole size if:
- Your strap button is smaller than usual
- You use Schaller-style strap locks or similar hardware
- Your current strap feels too tight to install
- Your strap hole feels too loose around the button
- You need a no-slice leather end for a locking system

The easiest way to check the diameter of your strap button or strap lock is to use a caliper. This gives you a more accurate measurement than guessing by eye.
Important: Do not force a strap onto hardware that does not fit properly. It can damage the leather or make the strap less secure.
Sliced vs. No-Slice Leather Ends
Leather end options: The guide below shows the difference between sliced and no-slice guitar strap leather ends, and when each option makes the most sense.
- Sliced leather ends are our standard option. They make it easier to attach and remove the strap from regular strap buttons.
- No-slice leather ends can be a better choice for some strap lock systems, where the locking mechanism holds the strap in place.

At Pardo Guitar Straps, every strap is made to order. That allows us to adapt small details like the hole diameter or the leather end finish.
You can request:

Final Thoughts: Choose the Right Fit
The standard 8 mm (5/16") hole is the right choice for most guitar straps. However, if you use strap locks or custom hardware, measuring before ordering is the safest option.
If you need a different hole size or a no-slice leather end, we can make your strap to match your guitar and hardware properly.
