The numbering of the size corresponds to the measured bearing rim circumference from edge to edge of the freshly prepared hoof.
For horses and bigger ponys we have a round shape (F for Front) and a longish shape (R for Rear).
For smaller ponys we have a mixed form of front and rear hoof shape (U for Uni)
F sizes: 290-400 mm in 10 mm steps
R sizes: 285-375 mm in 10 mm steps
U sizes: 225-275 mm in 10 mm steps
