Sizes and Shapes

To determine the correct horseshoe size for your horse, the hoof should ideally be unshod. The hoof should also be trimmed and prepared so that the horseshoe could be applied in the next step. If measurements are taken on a shod or untrimmed hoof, the result may not be accurate.

To determine the correct horseshoe size, you need the width and the length of the hoof. The widest point of the hoof is usually located slightly behind the tip of the frog .

There are two ways to find the right horseshoe size: you can either measure the hoof with a tape measure or ruler, or use our practical templates. We provide separate templates for round horseshoes, oval horseshoes, and STS horseshoes. For our open-toe horseshoes, templates are not available, so the hoof needs to be measured with a tape measure or ruler. When choosing open-toe horseshoes, please make sure to pay close attention to the position of the central bar.

The hoof width is measured at the widest point of the hoof, which is usually located slightly behind the tip of the frog. The hoof length runs from the tip of the toe to the end of the heels. Accurate measurements in millimeters are important. Ideally, the hoof should be freshly trimmed when taking measurements. If this is not possible, you can also use the previous horseshoe as a reference. If you are unsure, we recommend ordering two sizes to compare.

No. There is no universal standard for horseshoe sizes. Each manufacturer uses its own size charts and model shapes. For this reason, it is important not to rely solely on the stated size, but always compare the actual hoof measurements in millimeters or inches with the manufacturer’s specifications. To help with this, you will find the exact dimensions of our Duplo horseshoes listed earlier on this page.

The exact dimensions of a horseshoe vary depending on the manufacturer and the model. For our own horseshoes, you will find the corresponding measurements in mm and inches listed on this page.

To choose the correct horseshoe shape, look at the underside of the hoof as a whole and assess whether it appears more round or oval. In most cases, oval horseshoes are more suitable for the hind hooves, while round horseshoes and special shapes with a straight toe (STS) or an open toe are typically used on the front hooves. As always, exceptions can occur.

Our composite horseshoes with a straight toe, known as Straight Toe Shoes (STS), allow the horseshoe to be set slightly further backwards, which can help achieve an earlier breakover point . For this reason, the decision to use an STS shoe is not based solely on hoof shape, but also on the horse’s individual movement mechanics. On STS models, the quarter clips are set slightly further back than on our standard round shape.

In general, the selection of the appropriate horseshoe size and shape should be made in close consultation with a farrier or hoof care specialist. While many horse owners research suitable horseshoes online, the final decision should always take factors such as hoof balance, conformation, movement, and intended use into account. Proper fitting and professional application are essential to help prevent imbalance, excessive strain, or long-term hoof problems.

An incorrect horseshoe size or shape can negatively affect hoof health. Horseshoes that are too small can cause constriction, while shoes that are too large increase the risk of the horse stepping on them or catching them. Over time, poorly fitting horseshoes may lead to hoof wall cracks, contracted heels, uneven loading, and even lameness. Choosing the correct horseshoe and checking the fit regularly are therefore essential for maintaining the horse’s hoof health.

The selection of a suitable horseshoe is based on the shape and measurements of the hoof, together with our size chart. These details help determine an appropriate horseshoe for your horse.

When choosing a horseshoe, it is important to consider how a shoe should typically fit: in most cases, it follows the outer contour of the hoof and provides sufficient support in the heel area without being too long, as excessive length can increase the risk of the horse stepping on the shoe or injuring itself. Depending on the individual hoof, however, it may sometimes be advisable to choose a slightly wider or longer shoe. This assessment should be made by the professional working with the horse.

In addition to the basic measurements, several other factors should also be considered:

• For nailed horseshoes, the nailing slots must align correctly with the white line.
• For horseshoes with threaded holes in the heel area, make sure that the threads are not positioned too far back. Otherwise, the risk of the horse stepping on the shoe increases, and studs may create unwanted pressure on sensitive parts of the hoof.
• If a glue-on horseshoe is planned, allow for approximately 1 mm of additional material in the area of the weld seam.

Whether a horseshoe fits properly or can be adjusted to fit cannot be determined in general terms. Ultimately, the overall situation of the individual horse is always decisive.

If no shape or size appears to fit at first, this does not mean that a suitable solution cannot be found. With the necessary craftsmanship and, if required, the right accessories, a horseshoe can often be individually adjusted.

The plastic coating of Duplo horseshoes can be ground down in specific areas or expanded by adding material using welded plastic strips (extensions). This allows the horseshoe to be lengthened or widened. Duplo horseshoes with a metal core can also be forged slightly narrower or wider, similar to traditional steel shoes.
