Measure once, ride right.

Measure in a straight line from the centre of the saddle nail (the silver stud on the pommel) to the centre of the cantle. 16.5"–18" is the typical adult range. If you ride between disciplines, size down for jumping and up for dressage.

Measured between the points of the tree. Medium (M) suits most warmbloods and ISH types. Medium-Wide (MW) for cobs and chunkier sport horses. Narrow (N) for TBs and finer Arabs. A qualified saddler should sign off before you ride in earnest.

Sit in the saddle in your normal boots. Your knee should sit on the flap with 2–3 cm of leather in front of the kneecap. Short riders need a short flap, long-femur riders a long flap — labels alone won't tell you.

Wool-flocked panels can be re-balanced by a saddler — ideal for changing horses. Air-flock and foam panels are lighter but harder to adjust. Look at the underside photos before you buy.

Run a soft tape from the bit ring, up over the poll, down to the other bit ring. Cob ≈ 90–98 cm. Full ≈ 98–108 cm. Warmblood ≈ 108+ cm.

Measure two fingers below the cheekbone, all the way around the muzzle. Cob ≈ 34–38 cm. Full ≈ 38–42 cm. Warmblood ≈ 42+ cm. Two fingers should slide easily under a fastened noseband.

Run a tape from the back of one ear, across the forehead, to the back of the other ear. Add 1 cm of breathing room. Cob ≈ 36 cm, Full ≈ 39 cm, Warmblood ≈ 42 cm.

Width of the mouthpiece in millimetres or inches. Most warmbloods sit at 5.5" (140 mm), TBs at 5" (125 mm). The bit should peek 3–5 mm past the corner of the mouth on each side — no pinching, no sliding.

Measure from the centre of the chest, along the side of the horse, to the point of the buttock. 6'0" suits a 14.2hh pony, 6'9" most 16hh ISH/TBs, 7'0" a chunky warmblood, 7'3"+ for the big lads. Continental = back length × 2.54.

Detachable necks are sized to match the rug body. If you're buying a stand-alone neck cover, measure from withers to poll along the crest.

Lightweight 0–100 g for autumn and spring. Medium 150–250 g for an Irish winter on a clipped horse. Heavy 300–400 g for fully clipped horses in deep frost. Always layer rather than over-fill — easier to add than remove.

1000mm waterproof handles showers. 3000mm+ handles Irish winter sideways rain. Look for taped seams and re-proofing history in the listing notes.

Boot sizing runs about half a size smaller than street shoes — your foot needs to be snug, not loose. If you're between sizes, size up only if your usual shoe runs narrow.

Measure in cm around the widest part of your calf, wearing breeches and a half-chap-thickness sock. Standard ≈ 36–38 cm. Slim ≈ 32–35 cm. Wide ≈ 39 cm+. New leather drops 1–1.5 cm with wear; older second-hand boots have already done their dropping.

Stand barefoot. Measure from the floor up the back of your leg to the bend of the knee, then add 2–3 cm for the heel of the boot and the dropped leather. Too tall pinches the back of the knee; too short looks dressy and won't seal against the saddle flap.

Measure calf circumference at the widest point AND the height from the floor (in habitual paddock boots) to the bend of the knee. Both numbers appear on every ECI half-chap listing.

Wrap a soft tape around the largest part of your head — about 2 cm above the eyebrows. Most adults sit between 56–60 cm. Hats are then sized by harness adjustability around that number.

PAS 015:2011, VG1 01.040 2014-12, ASTM F1163 or SNELL E2016. Anything older or unmarked is refused. Pony Club, BE and IPC rules vary by discipline — check before buying for competition.

BETA Level 3 (purple label) is the standard for cross-country, hunting and racing. Sized by chest, back length and front length — all three should be measured separately. Re-checked after any hard fall.

Body protectors have a 3–5 year working life from manufacture date. Hats with any impact, drop or sun-bleach should be retired. Date and serial appear on every ECI safety listing.
