A cinch is non-negotiable. It makes everything go right, or spectacularly wrong. While any cinch can be functional, not every western girth is ideal. Like any other piece of horse tack, it has an important job to do, and needs to fit right to do its job right.
Unfortunately, it's not a one-size-fits-all situation. It's not a precise measurement, and you don't need to get a new cinch every time your horse gains or loses a few pounds, but for a cinch to do its job, it needs to be the right length. Like Goldilocks, you don't want it too short or too long. Just right.
A just right cinch will keep your saddle stable, centered and won't sore your horse.
Why Proper Cinch Fit Matters
A properly fitted horse cinch should:
- Keep your saddle centered and stable
- Prevent rolling or shifting during your ride
- Reduce the risk of galling and soreness
- Allow for balanced pressure and comfort
When it comes to measuring your horse for a cinch, it's not complicated, but it is important. Follow along while we go through the steps to figure out how to find that perfect length for a western cinch.
What You’ll Need
Before you start measuring for your western cinch, gather:
- Soft vinyl measuring tape (preferred)
- OR a piece of baling twine or string
- Marker (if using twine)
- Your saddle
- Your horse
- Step-by-Step: How to Measure for a Western Cinch
Step 1: Secure Your Horse
- Tie your horse in a safe, level area
- Make sure they’re standing square and relaxed
Step 2: Place Your Saddle
- Set your saddle in its correct riding position
- Ensure it’s sitting naturally where you normally ride
Step 3: Measure Dee to Dee
- Run your soft measuring tape from one saddle dee ring
- Go underneath the horse, where the cinch will sit
- Continue to the opposite saddle dee ring
Tip:
If using twine, mark the length and measure it afterward.
Step 4: Subtract 16 Inches
- Take your total measurement
- Subtract 16 inches
This gives you your ideal western cinch size
Why Subtract 16 Inches?
That 16 inches accounts for proper spacing on both sides of your saddle:
- About 8 inches of latigo and 8 inches of off billet from the saddle dee to the cinch buckle
- Total of 16 inches across both sides
This spacing:
- Keeps bulky leather out from under your legs
-
Maintains better leverage and saddle stability
Maintaining 8 inches on both sides from the cinch buckle to your saddle dee prevents having too much leather underneath your legs while riding.
Fit Check: Is Your Cinch the Right Length?
Once you have your horse cinch, double-check the fit:
1. The 8-Inch Rule
- There should be ~8 inches between the saddle dee and the cinch buckle on each side
2. The Hang Test
- Let the cinch hang naturally from the saddle
- The buckle should sit level with the middle of the cannon bone
Common Mistake: Cinch Too Long
Many riders unknowingly use a western girth that’s too long. It may hold the saddle in place, but it creates problems:
Excess latigo leather bunches under your leg
- Reduced leverage due to lower pull point
- Increased saddle movement over time
Result: A saddle that shifts, rolls, and becomes less secure the longer you ride
Common Mistake: Cinch Too Short
Some riders unknowingly use a cinch that’s too short, which also creates problems:
- Pressure is concentrated in a smaller area, leading to pinching
- Buckles sit too low, increasing risk of rubs and irritation
- Reduced leverage when tightening the saddle
- Uneven tension from side to side
Result: A horse that becomes uncomfortable, with a saddle that feels unbalanced and harder to secure over time
What “Just Right” Looks Like
A properly sized western cinch should:
- Sit evenly on both sides
- Keep hardware positioned away from your leg
- Maintain consistent contact without pinching or rubbing
- Support a balanced ride that's effective and comfortable for your horse
While it may take some trial and error to find just the right cinch for you and your horse (may we suggest you check out this blog post that talks about different types of cinches?), the first step is to find the right length. From there, maybe a mohair cinch is what you're looking for, or an Airflex or a Smart Cinch. We've got ropers and straight cinches, roller buckles and Jeremiah Watt buckles. From fancy to functional, find the cinch you're looking for here.
