Horse Body Condition Score Calculator

How to assess each of the six sites

Work in the same order every time so your records stay comparable. Look first, then palpate with flat fingers and firm, even pressure. Fat cover cannot be judged by eye alone.

Neck

Thin horses show the bone structure of the neck and a very trim throatlatch. At a moderate score the neck blends smoothly into the shoulder. As fat increases it builds along the top of the neck.

Withers

Sharp and bony when thin, rounded at moderate, filled and eventually bulging when fat. Wither prominence varies by breed, so use this site with care on a very typey horse.

Behind the shoulder

When thin, the outline of the shoulder blade is easy to see. At moderate the shoulder blends smoothly into the body. When fat, the area fills flush with the ribs.

Ribs

Visible with no padding when thin. At moderate they are not easily visible but are easily felt. When fat, they are difficult or impossible to find. Visible ribs can be normal in weanlings and yearlings.

Loin and back

A bony ridge or hollow along the loin indicates a low score. A flat loin with no crease or ridge is moderate. A crease down the loin indicates a high score.

Tailhead

Prominent and easy to outline when thin. At moderate, fat around the dock feels spongy. When fat it feels soft and begins to bulge. Tailhead prominence also depends on breed.

The belly is deliberately not assessed. It changes with gut fill and forage intake and is an unreliable place to judge fat.

Whole-horse score descriptions

These descriptions and acceptability notes follow the Merck Veterinary Manual’s current body condition score table for horses. Compare your horse against them as a whole animal, then use Step 2 in the calculator. Where conformation, late pregnancy or muscling makes one or two sites unreliable, place more weight on the remaining sites rather than discarding the assessment.

• 1 — Emaciated. Spinous processes, ribs, tailhead and hip bones all very prominent. Bone structure of neck, withers and shoulders easily visible. No fat palpable over the loin. Unacceptable under any circumstance, with severe risk of refeeding problems.
• 2 — Very thin. Spinous processes slightly rounded but visible. Ribs, tailhead and hip bones prominent. Unacceptable, though it may reflect illness or debilitation; risk of refeeding problems.
• 3 — Thin. Some fat build-up on the spinous processes but loin and tailhead still prominent. Neck vertebrae not visible but easily felt. Ribs still easily visible. Not desirable for optimal health and well-being.
• 4 — Lean. Slight bony ridge over the loin or flat, faint rib outline visible. Fat palpable at the tailhead. Hip bones not easily visible. May be acceptable, especially for anaerobic performance such as racing.
• 5 — Moderate. Loin flat with no crease or ridge. Ribs not easily visible but easily felt. Tailhead fat spongy. Shoulders and neck blend smoothly into the body. Acceptable for all.
• 6 — Moderately fleshy. Possible slight crease down the loin. Ribs palpable with light pressure. Some fat on the sides of the withers, the neck and behind the shoulder. The acceptable upper limit of condition, and ideal for broodmares.
• 7 — Fleshy. Possible crease down the loin, ribs difficult to feel, palpable fat along the withers, behind the shoulder and along the neck. Unacceptable and considered obese, with reduced heat and exercise tolerance and increased risk of metabolic disease.
• 8 — Fat. Crease may be visible down the back. Ribs very difficult to feel, tailhead fat very soft, noticeable thickening of the neck. Unacceptable and considered obese, with increased risk of metabolic disease and laminitis.
• 9 — Obese. Obvious crease down the loin, fat bulging around the tailhead, withers, behind the shoulders and along the neck, flank filled with fat. Unacceptable and considered morbidly obese, with increased risk of laminitis, other metabolic disorders and colic.

There is no single correct target score for every horse. Those acceptability notes are general guidance for horses as a group. The right target for one animal depends on age, breed and type, workload and discipline, season, pregnancy or lactation, dental status and existing health conditions, and setting it is a job for your veterinarian or a qualified equine nutrition professional who has examined the horse. This page does not set a target for you.

Why this page will not calculate the score for you

The original Henneke work scores the whole animal, and the method accepts that some sites carry more weight than others when conformation or pregnancy makes a site unreliable. No validated equal weighting of the six sites exists, so averaging them would produce an invented number dressed up as a result. The worksheet makes sure you look at all six and shows you the range you observed. You then make the judgement, which is what the published method actually asks for.

If your site values span three points or more, or your chosen whole-horse score falls outside the range you recorded at the sites, the tool flags low confidence and recommends reassessment with a trained assessor. It still does not calculate anything.

What the Cresty Neck Score adds, and its limits

The Cresty Neck Score rates fat along the top of the neck on a 0 to 5 scale. It is worth recording because neck fat does not always track total body fat: some horses carry a heavy crest at an otherwise moderate body condition.

• 0 — no crest visible and none can be felt.
• 1 — no visible crest, but slight filling can be felt.
• 2 — a small crest, filled fairly evenly from poll to withers, that can be cupped in one hand and bent side to side.
• 3 — enlarged and thickened, heavier mid-neck than at the poll or withers, filling a cupped hand and hard to bend.
• 4 — grossly enlarged; cannot be cupped in one hand or bent, and may show creases across the topline.
• 5 — so large that it permanently droops to one side.

Important limit on this evidence. The work supporting the Cresty Neck Score as a predictor of insulin dysregulation independent of body condition score was carried out in ponies, not in a broad cross-section of horse breeds and types. Ponies are over-represented among animals with insulin dysregulation, so how the score performs in, for example, a Thoroughbred, a Warmblood or a draft horse cannot be assumed to be the same. Treat a high crest score as a reason to raise the subject with your veterinarian, not as a result that transfers automatically to every horse.

What this tool cannot do

• It does not calculate a score. The whole-horse score in your summary is the one you chose. Nothing is averaged or weighted.
• It cannot diagnose. The ECEIM consensus statement describes equine metabolic syndrome not as a disease in itself but as a collection of risk factors for endocrinopathic laminitis, with diagnosis resting partly on history and clinical examination and partly on laboratory testing. Insulin dysregulation, PPID and laminitis are identified by a veterinarian, not by a condition score.
• A moderate score does not clear your horse. Insulin dysregulation also occurs in horses that are not overweight.
• Owner scoring is unreliable on its own. When owners and an experienced examiner scored the same animals in a 2022 study, agreement on both body condition score and cresty neck score was poor.
• It is not a weight. Condition score describes fat cover, not pounds. Use a weight estimate alongside it, not instead of it.
• It gives no ration. This page does not calculate feed amounts, target weights, or supplements.

Practical next steps

1. Repeat the assessment every two to four weeks, at the same time of day, in the same light, by the same person.
2. Photograph your horse from the side and from behind each time. Slow change is far easier to see in photos than in memory.
3. Track a weight tape or heart girth measurement alongside it, and write both down.
4. Bring your records, dates and photos to your next veterinary visit. A trend over months is more useful than a single number.
5. Ask your veterinarian or a qualified equine nutritionist to score your horse alongside you once, so you can calibrate your hands against theirs and agree a target for this individual animal.

When to call a veterinarian

Treat as an emergency and call immediately if your horse shows lameness that is worse when turning, shifting lameness at rest, heat in the feet, an increased digital pulse, a reluctant or hesitant gait, or a sawhorse stance with the front feet stretched forward. The AAEP advises treating suspected laminitis as a medical emergency and notifying your veterinarian immediately. Call immediately as well if your horse has broken into stored grain, before any signs appear.

Book a veterinary appointment if your assessment sits at 3 or below, if weight has changed with no change in feed or work, if the crest has thickened over recent weeks, if an older horse is losing topline, or if you are unsure what you are feeling. A horse at 1 to 3 should be examined before any increase in feed, because rapid refeeding of a starved horse can cause refeeding syndrome, which can be fatal.

Common questions

Is 5 the right score for my horse?

Not necessarily. Merck’s table describes 5 as acceptable for all, and 4 and 6 as acceptable in defined circumstances, but that is general guidance for horses as a group. An individual target depends on age, type, workload, season, reproductive status and health, and should be set by your veterinarian or a qualified equine nutrition professional.

Why are half points not offered?

Whole numbers only, to avoid implying more precision than hands-on assessment supports. If your veterinarian, nutritionist or organization records half points such as 4.5 or 6.5, keep using their convention on their paperwork and treat this page as a rough worksheet rather than a more precise instrument.

Can I score a horse just by looking?

Not reliably. A thick winter coat, a heavy muscle pattern, or a dark coat in poor light can all hide or exaggerate condition. Fat cover has to be felt.

Does a weight tape give me a condition score?

No. A tape estimates bodyweight. Two horses of identical weight can carry very different amounts of fat.

My horse sits mid-scale but has a thick crest. What does that mean?

Fat is concentrated on the neck rather than spread evenly. That pattern is worth raising with your veterinarian, who can advise whether blood testing makes sense. Bear in mind the supporting research was done in ponies.

Does a big belly mean a high score?

Not necessarily. Belly shape changes with gut fill, forage type and pregnancy, so it is not one of the six sites.
