The size of a Duplo Horseshoe is always measured at its widest point. The smallest Duplo is currently 98mm wide, the largest one is 198mm. The interval between sizes is 4mm - you will therefore find models of 110mm and 114mm but nothing in-between. If your horse needs an in-between size, you can easily adjust a slightly too large horseshoe with an angle grinder.

Duplo Horseshoes are not only available in numerous sizes but also in three different shapes. The round and STS horseshoes generally fit the front hooves, the oval models are rather made for hind hooves. As always: The exception prooves the rule.

In order to determine the correct Duplo size for your horse, it should be unshoed. The hoof should be correctly trimmed so that a new horseshoe could be applied. If you measure an untrimmed or shoed hoof, you might not get the desirable exact results.

First, use a measuring tape or a ruler to measure the widest point of the hoof's bottom surface which usually is to be found at a short distance behind the frog apex.

Then, take a look at the sole as a whole and decide whether it is rather round or oval.

With these two results - the hoof width in millimeters and the hoof shape - you can choose your favorite Duplo model in your horse's size.

With our free Duplo templates, choosing a correctly sized horseshoe gets even easier.

There's one template for round horseshoes, one template for oval horseshoes and one template for STS horseshoes available. Every template consists of two pages in an A4 format that you can print and glue together. You can use the template in various ways:

• You place the hoof on an empty sheet of paper and trace the hoof shape. Then you cut the shape out and place it on the printed template.
• You can place the printed template directly on the hoof (or place hoof on the template) and trace the hoof shape.
• You can glue the printed template on a cardboard to make it more solid, and then trace the hoof shape.
• You can print the template more than once and cut out the sizes that probably come into consideration. Then, you place the cut-out shapes directly on the hoof. This is the most time-consuming option, but probably also the most reliable one.

Please note: The templates fit our models with quarter clips. The shape of the un-clipped horseshoes varies minimally; however, you can also use the templates for these horseshoes.

Please use the small scale on the templates in order to check your printer settings.
