Horse height converter
One hand is four inches, or 10.16cm. So 13.2hh is 137.2cm, 14.2hh is 147.3cm and 15.2hh is 157.5cm, while 148cm is just over 14.2hh. Type any height however you say it out loud and it converts both ways.
Hands to centimetres: every height
A bare number with no unit is read by size: 60 or more is taken as centimetres, 25 to 59 as inches, and anything smaller as hands.
Every figure here is arithmetic: one hand is four inches, one inch is 2.54 cm exactly. The hand is defined as four inches by the Scottish Government’s own conversion table; the pony height limit is the FEI’s, quoted below; the British measuring rules are the Joint Measurement Board’s.
Pony or horse
The line is written in centimetres, not hands: a pony’s height at the withers must not exceed 148cm without shoes. That is 14 hands and 2.27 inches, so it sits a little above the 14.2hh most people quote: 14.2hh is 58 inches, or 147.32cm. A horse measuring exactly 14.2hh is a pony under this rule.
“Ponies' regulatory height at the withers must not exceed: 148cm without shoes (any measurement between 148.1cm and 148.9cm will be rounded down to 148.0cm); and 149cm with shoes.”, from FEI Veterinary Regulations 2026, Chapter IX, Article 1080.2
Why 15.2hh is not fifteen point two
A hand is four inches. The digit after the point is not a decimal fraction of a hand, it is a count of leftover inches, so it only ever runs .0, .1, .2, .3 and then rolls over to the next whole hand. There's no such height as 15.4hh, and 15.2hh means fifteen hands and two inches: 62 inches, or 157.5cm.
This is why converting in your head goes wrong. Fifteen point two hands would be 154.4cm if the fraction were a decimal. It is not, and the true answer is three centimetres taller.
How tall is a horse?
Most riding horses in Britain stand between about 15hh and 17hh, or roughly 152cm to 173cm at the withers, and anything 14.2hh (148cm) or under counts as a pony. The range across breeds is wide, and the breed societies set the limits for their own.
| Type | Typical height | In centimetres |
|---|---|---|
| Shetland | Up to 42 inches (10.2hh) | Up to 107cm |
| Welsh Section A | Up to 12hh | Up to 122cm |
| Connemara | 12.2hh to 14.2hh | 127cm to 148cm |
| Thoroughbred | Usually 15.2hh to 17hh | 157cm to 173cm |
| Warmblood | Usually 16hh to 17.2hh | 163cm to 178cm |
| Shire stallion | 17hh and over | 173cm and over |
How a horse is measured, officially
At the withers, the ridge between the shoulder blades, with the horse standing square on a level surface. Not at the head, which moves, and not at the highest point of the back. Most explanations stop there. The rules that govern a British show height are considerably tighter, and they are worth knowing even if you are only measuring at home with a stick against a wall.
In Britain, official heights are issued by the Joint Measurement Board. Its rules, effective from 1 January 2026, pin down the point on the horse anatomically: the measurement “must be taken at the highest point of the withers, (i.e. immediately above the spinous process of the 5th thoracic vertebra)”, which the measurer may identify by palpation and mark before measuring.
Four things then decide the number you get.
- The shoes come off. The horse
must have had all four shoes removed and the feet must be correctly prepared and balanced as for shoeing with the wall taken down level with the bearing edge of the sole
. - The head is held within a window. It must be in its natural position,
positioned so that the eye is neither more than 8 cm (3 in) below, nor more than 8 cm (3 in) above the highest point of the withers
. Raise the head and you lower the withers, which is precisely why the rule exists. - The horse stands square. All four feet taking weight, front legs parallel and perpendicular, the front toes in line to within 1.5cm, and the hind toes no more than 15cm out of line with each other.
- The lowest figure is the one recorded. The result submitted
must be the lowest truly relaxed height of the horse or pony in the opinion of the Official Measurer
, once it has settled and relaxed on the pad.
The stick matters too: it must carry a spirit level, be shod with metal, and have been certified by a Trading Standards Officer within the previous four calendar years. Horses cannot be measured at all before they are four years old, and a result differing from a previous one by 2cm or more can trigger a recall.
One current point that catches people out: since the 2026 rules, a paper certificate is no longer proof of anything. The JMB states that measurement certificates are no longer valid proof of any Measurement, the JMB’s Register represents the sole valid proof
.
So a horse can measure differently on two different days, and the official answer is deliberately the settled, relaxed reading, not a high one taken while the horse is tense. The FEI adds its own rounding rule and a separate allowance for shoes, quoted above.
The breed groups are set out in how horse breeds are grouped, and the cost of keeping one in what a horse costs.
Buying for someone else
If you are here because you are shopping, not measuring, you do not need to know the horse’s height at all. The horse gifts are sorted by occasion and budget, the horse prints are the sixteen artworks that need no photo, and horse memorial gifts mark a horse that has gone. For a present that assumes no horse of your own, see gifts for horse lovers.
Pony, or a small horse
Height is the line, not age and not breed. A fully grown Welsh pony stays under it for life, while some horse breeds only cross it as adults, and a yearling measuring 13hh today is not a pony because of it. For the words used about sex and age instead of size, see what a gelding is.
Hands, and why Britain still uses them
The hand comes from exactly what it sounds like, the breadth of a human palm, standardised at four inches. Most of the world measures horses in centimetres and the rulebooks are written that way, but British and Irish yards still speak in hands, and both appear on the same passport, which is why this page exists.
