Choosing the right boxing glove size is one of the most important decisions you'll make as a boxer, whether you're just starting out or gearing up for competition. Gloves that are too small won't protect your hands properly, while gloves that are too large can throw off your technique and tire your arms out faster. This guide breaks down everything you need to know about boxing glove sizing in the UK, from oz weights to fit tips.
Understanding Glove Weight (oz)
Boxing gloves are measured in ounces (oz), which refers to the total weight of the glove including padding, not your hand size. The general rule is simple: the heavier the glove, the more padding it has, and the better protection it offers for both you and your sparring partner.
8oz to 10oz: Competition gloves for licensed adult boxers in lighter weight classes. Not recommended for training.
12oz: Ideal for smaller adults, lighter-weight boxers, and bag work. A popular choice for cardio boxing and technique training.
14oz: The most common all-round training size for adults under around 12 stone (75kg). Great for pad work, bag work, and light sparring.
16oz: The standard sparring glove size for most adult boxers. Extra padding protects both you and your partner during contact training.
18oz to 20oz: Recommended for heavier boxers (over 14 stone/90kg) or for extended sparring sessions where maximum protection is needed.
How to Choose Based on What You're Doing
Bag work and pad work: 12oz to 14oz gloves give you enough protection without slowing down your hand speed.
Sparring: Always size up. 16oz is the widely accepted minimum for sparring in most UK boxing gyms, and some clubs require 18oz or more.
Competition: Amateur competition glove weight is usually set by your governing body and weight class, so check with your club before buying.
Kids and juniors: Junior gloves typically range from 6oz to 10oz depending on age and hand size. Always check the product's specific sizing before buying for a child.
Sizing by Body Weight
As a general starting point: under 9 stone (57kg), look at 10oz to 12oz. Between 9 and 12 stone (57 to 75kg), 12oz to 14oz suits most people. Between 12 and 14 stone (75 to 90kg), go for 14oz to 16oz. Over 14 stone (90kg plus), 16oz to 18oz or heavier is usually more comfortable.
This is a starting point, not a strict rule. Your experience level, wrist size, and what you're using the gloves for all matter too. Take a look at our full boxing gloves collection to compare oz weights side by side.
Getting the Fit Right
Even the correct oz weight won't help if the glove itself doesn't fit well. Look for a snug fit around the knuckles with no dead space, but enough room to make a full fist comfortably. A secure wrist strap, whether hook-and-loop or lace-up, keeps your wrist supported and stops the glove twisting on impact. Breathable lining matters too, especially if you train frequently, since sweat build-up in a poorly ventilated glove leads to faster wear and odour.
If you're between sizes, sizing up is usually the safer choice, especially for sparring or bag work, since extra padding protects your hands and wrists over long-term training.
