Decoding Tree Sizes

31 Mar
A common issue saddle shoppers have is determining which tree size their horse needs – especially because a certain tree in one brand may not correspond to the same size in another brand. This can lead to some confusion! And rightfully so!  It only makes sense that a 31cm tree in Prestige would be the same as a 31 cm tree in a Stubben.  However, that is NOT the case.  So, we have done our best to help you decode some tree sizes for some of our most popular saddle brands.

27cm – extra narrow

Prestige Boston

Prestige saddles are able to be adjusted by authorized dealers up or down by 2cm. As an authorized Prestige dealer we would be happy to help you make Prestige tree adjustments that you may need. 

If you are not sure if your Prestige saddle fits properly we would be happy to do a saddle fit evaluation and to take a look at your saddle fit photos.

We do still recommend having a qualified saddle fitter see your horse in person but from the photos we CAN usually determine if the tree size is correct for your horse, based on the balance and position of the saddle on your horse’s back. We can NOT usually determine how the panels are fitting your horse’s back, bridging, gaps or pressure points. These are things that must be determined in person.

In order to be able to see the balance, we ask for the following: Photos of the WHOLE horse from the SIDE standing on LEVEL ground INCLUDING the horse’s hooves and head. Let me stress this again: We need to see the entire horse in the photo in order to get an idea of the overall balance of the saddle. Put the saddle in the position that you would normally ride and tighten the girth. Do not use a saddle pad. If your horse has an unusual back conformation, you are welcome to send photos of the horse’s back without the saddle. See the example picture below!

You can send those pictures as well as Prestige tree adjustment requests to and our knowledgeable staff will help you determine if the tree in your Prestige saddle needs adjusting. 

31cm – narrow to extra narrow

32cm – on the narrower side of medium, typically a horse with good withers but a medium to narrow back, like a typical TB type horse

33cm – medium

34cm – generous medium, fits many horses well

35cm – wide

36cm – extra wide

37cm – extra extra wide


Stackhouse Monoflap Jumping Saddle

Although Stackhouse saddles come in standard tree sizes narrow, medium, and wide. Our experience is that to Stackhouse, an “average” or “medium” tree is meant for a more typical Thoroughbred. Your horse may need to go up a tree size from what he or she typically wears.




Courbette Vision

Courbette saddles can come with a few different types of trees.  A distinct tree that they make is called a “flex tree” which means that it can adjust to your horse, within reason. It starts out at about a medium tree size but, is flexible and once it is girthed up on and you are sitting in it, will adjust to anywhere from a medium-narrow to medium-wide. There is also an extra wide version of the flex tree and the standard style trees.

29cm -narrow

30cm – medium narrow

31cm – medium

32cm – medium wide

33cm- wide

34cm – extra wide

We know that finding the right saddle fit for you and your horse can be a process so let us help!  VTO Saddlery has a wonderful test ride program that allows you to ride in the saddle FIRST before deciding if its your perfect match.  You can visit us online or in store for a wide selection of saddles and saddle accessories!
