Precision saddle fit · LiDAR
Now in private betaKnow your horse.
Equimorphic reads your horse’s back in three dimensions and returns the numbers a saddle tree actually has to match — gullet width, bar angle, rock, and how far the two sides differ. It takes a walk down the barn aisle with the phone already in your pocket.

What we do
A saddle that doesn’t fit is a soundness problem.
Pressure in the wrong place shows up long before anybody calls it lameness — a cold back, a hollowed topline, a horse that won’t come through from behind. The usual remedy is to book a fitter: weeks out, a few hundred dollars a visit, and a result that comes down to whose hands were on the wither tracing.
Equimorphic replaces the tracing. Your phone captures the whole back as a three-dimensional surface, and that surface is measured the same way every single time — on your horse, on your schedule, for a fraction of a call-out.
It is the same measurement a good fitter takes. It just doesn’t take an afternoon.
Repeatable
The same back, scanned twice, measures the same twice. No drift between one fitter's eye and the next, no reading a wire template by hand.
Complete
A continuous surface rather than three or four tracings — so the shape between the tracings is measured too, not interpolated.
Yours to keep
Every scan stays on file against the horse. Scan again after a season of work, or after a lay-up, and see exactly what changed.
How it works
Three steps, one of them yours.
01 · Scan
Walk the phone slowly along your horse's back. The app captures depth directly — no chalk marks, no wire, no second person holding a template steady.
02 · Measure
The scan uploads and is sectioned automatically: through the withers, across the bearing surface, and at the back of the panel. Each section is then fitted for width and angle.
03 · Fit
A report comes back with the measurements and the sections they were taken from. Hand it to your saddler, send it to a seller, or check the saddle already in your tack room against it.
Scanning runs on iPhone and iPad. Everything after the scan — reports, history, re-running an old scan against a new measurement — works in any browser, on one account that follows you between the barn and the desk.
The report
Numbers, not adjectives.
“A touch narrow through the shoulder” is an opinion. A gullet width is a number — and a number can be checked against a tree, argued with, and compared to the same horse six months from now.
Every report carries the cross-sections it was measured from, so you can see the shape the numbers came out of rather than taking them on faith.

Saddle parameters
Illustrative- Gullet width
- 6.50 in
- Bar angle
- 88.3°
- Wither clearance
- 2.4 in
- Rock
- 0.75 in
- Asymmetry, L to R
- 0.3°
- Fit residual
- 0.31 mm
Fit residual is how closely the fitted tree follows the horse’s actual surface. Inches or millimetres, degrees or radians — whichever you work in.
Who we are
“The horse is the hard part. The measurement should be the easy part.”
Equimorphic is a small team building measurement tools for people who ride. We came at saddle fit from the geometry side and found an industry still working from wire templates and waiting lists.
