Table of Shaft Lengths and Widths

Table

One of the first questions people ask when they go out looking for a carriage is "How do I know if it will fit?" Over the years there have been several charts printed to aid people by giving dimensions to help in buying the right size. This is a compilation of  some of that information into one chart. How is this kind of chart possible? While horses body types are not identical, there is a dimensional ratio between various parts of the body compared with the height at the withers and this is adequately similar for the purposes of shaft design for different sizes of horse or pony.  

What parts of the body need to be considered? Wither height, width at the shoulder, width at the saddle girth, croup width, length of trunk from point of shoulder to buttock and location of the stifle.  An additional consideration is normal length of stride. Taking all these factors together helps define the space needed to give the horse sufficient room to move and to be comfortable, while also allowing room for the harness, and some leeway for a slightly larger or smaller animal.  The information in this chart defines approximate dimensions needed to build or buy a traditional style of two-wheeled single horse vehicles or 4-wheeled pole type vehicles to fit a wide range of horse sizes. Adjustments may need to be made to accommodate heavy draft type horses, donkeys and small ponies or mini-horses. Vehicles designed for specific purposes like the modern marathon vehicle or an antique gig will often differ in dimensions to meet their specific needs. For example: marathon shafts are shorter and end at the saddle girth, or some gigs are made with narrower widths between the shafts. The size and design of the harness may also affect how a vehicle fits. A bulky saddle could require more space between the shafts. Style of breeching may affect the position of the breeching staple. Also the chart describes wheel height for two-wheeled vehicles. Wheels will be smaller on four-wheeled vehicles.
