In equestrian contexts, offside refers to the right-hand side of the horse — the side that is away from the rider when mounting and the side traditionally avoided when approaching a horse to saddle or handle it. It is the counterpart to the nearside, which is the horse’s left.
Origin of the Term
The convention of offside and nearside has roots in practical history. Most riders are right-handed, and the custom of mounting from the left evolved partly because a mounted soldier’s sword hung on his left hip — swinging a right leg over was more practical and less likely to catch the blade. Over centuries, this became the universal standard in Western horsemanship traditions, and with it came the associated terminology.
The left became the ‘near’ side (the side nearest to the handler) and the right became the ‘off’ side (further away during most groundwork). Both terms persist in modern British and Irish yards as standard vocabulary, though their use is somewhat more common in traditional and competition environments than in casual stable conversation.
Practical Significance of the Offside
Most horses are handled predominantly from the nearside throughout their lives — tacked up, mounted, and led from the left. This creates a notable asymmetry in many horses. They are often more relaxed and familiar with contact on the nearside and can be noticeably less tolerant of handling, saddling, and girthing from the offside, particularly if their training has not addressed this deliberately.
Good horsemanship involves regularly working the horse from the offside. Rugging, grooming, and tacking up should be done from both sides so the horse builds equal confidence and acceptance. A horse that tenses or moves away when approached on the offside is signalling a gap in its handling, not a character flaw.
Mounting from the Offside
While nearside mounting is standard, there are situations where mounting from the offside is necessary — a damaged or sloped nearside terrain, an injury that makes it impractical, or working with horses in certain traditional cultures where offside mounting is normal. Horses that have been trained to accept mounting from both sides are more versatile and safer in unusual environments.
Teaching offside mounting is a worthwhile exercise for any horse in regular work. Begin by desensitising the horse to the mounting block on the right, running through the same sequence used from the left until the horse stands quietly and without anxiety.
Offside in Driving and Carriage Work
In driving, the terms nearside and offside are used to describe which horse is on which side in a pair or team. The nearside horse is on the left and the offside horse is on the right. This matters practically because in most countries, traffic drives on the left, and the driver sits to the right — meaning the offside horse is closest to oncoming traffic and often requires slightly different handling and temperament considerations.
Common Usage in Yard and Competition
Yard staff and competition officials routinely use nearside and offside when giving instructions. “Check the offside stirrup”, “the offside panel is slipping”, or “approach from the nearside” are all standard phrases. Understanding both terms immediately and without having to think about it is a marker of practical equestrian competence.
In veterinary contexts, the offside is sometimes abbreviated as “RHS” (right-hand side) in clinical notes, though nearside and offside remain preferred in everyday stable language.
Frequently Asked Questions
Why do horses seem more comfortable on the nearside than the offside?
Because that is the side they are handled from most consistently throughout their lives. From their first headcollar fitting to years of grooming, tacking, and mounting, the left side receives far more human contact and desensitisation work. The offside is, in most horses’ experience, simply less familiar. Regular, calm handling from the right side closes this gap over time.
Does it matter which side I lead my horse from?
Standard practice is to lead from the nearside (left), and this is expected in most competition and official contexts. However, it is genuinely good training to occasionally lead from the offside so the horse is comfortable being guided from either direction. A horse that can only be led from one side is limiting in emergency or practical situations.
Is offside the same in all countries?
The nearside/offside convention is consistent across British, Irish, Australian, and most European traditions: nearside is left, offside is right. It aligns with the universal practice of mounting from the left. American terminology is less likely to use these specific words in casual contexts, with “left side” and “right side” being more common, but the underlying convention of handling from the left is the same.
