What size boxing gloves should you choose? The complete oz guide
of reading
Quick answer: glove size depends on your body weight and your use. Basic rule: 12 oz under 65 kg (145 lb), 14 oz between 65 and 80 kg (145-175 lb), 16 oz above that or for sparring. Gloves are measured in ounces (oz) — the higher the number, the more padding.
What does the ounce (oz) mean on a boxing glove?
The ounce indicates the weight of the padding. The higher the number, the more padded and protective the glove. Measuring a size in weight may seem odd — here is why it is done that way.
The history of the first boxing gloves
To understand why boxing gloves are sized by weight, you have to go back to how they were originally made. Before modern foam, gloves were padded with horsehair. Manufacturers had no way of ensuring each glove contained the same amount of padding — other than by weighing it.
So an 8 oz glove held exactly the same amount of horsehair as any other 8 oz glove. That guaranteed a uniform level of protection. Over time those weights became the standard, and the governing bodies of boxing then codified specific weights for different levels of competition. Today, even though gloves are made with synthetic foam, the ounce system has stayed.
Ounce to gram conversion
One ounce is about 28.35 grams. A 16 oz glove therefore carries roughly 454 g of padding per hand, a 10 oz glove about 284 g.
The 5 glove sizes and what they are for
Which size for your body weight?
| Your weight | Bag / training | Sparring | Competition |
|---|---|---|---|
| Under 55 kg / 120 lb | 10 oz | 14 oz | 10 oz |
| 55 to 65 kg / 120-145 lb | 10 to 12 oz | 14 oz | 10 oz |
| 65 to 80 kg / 145-175 lb ★ | 12 to 14 oz | 14 to 16 oz | 10 to 12 oz |
| Over 80 kg / 175 lb | 14 to 16 oz | 16 oz | 12 oz |
For competition gloves, it is advised to take one size down from your usual training size. Why? Because the tighter the glove, the more the punch lands. Less space between hand and glove increases the hardness of the impact.
Conversely, for intensive sparring, go one size up: more padding protects your partners during hard rounds.
The sparring rule: never spar in 10 oz gloves or lighter. Most clubs require 14 oz minimum to avoid injuring a partner.
Sizing by hand length
You can also get a size indication by measuring the length from the crease at the base of the palm to the tip of the middle finger. This guide converts that measurement into the matching size in ounces.
Boxing glove sizes for children
Children's boxing gloves work differently: the weight in ounces corresponds more directly to the physical size of the glove. Here is the quick guide.
| Age | Recommended size |
|---|---|
| 3 to 4 years | 2 oz |
| 4 to 5 years | 4 oz |
| 5 to 7 years | 6 oz |
| 7 years to early teens | 8 oz |
Competition gloves: the official rules
At the vast majority of shows and competitions, gloves are supplied by the organiser. But if you box at amateur level, federations set precise sizes by weight category.
In the United States, for example, USA Boxing codifies glove size by category: fighters from Light Flyweight to Light Welterweight use 10 oz gloves. In the United Kingdom, England Boxing sets its own requirements, as does the French Boxing Federation in France.
Advice: always check the rules of your own federation before buying competition gloves — the requirements vary by weight category, by level and by country.
The sizes available on the market
Glove sizes are sold in 2 ounce steps. Each step up means 2 more ounces of padding in front of the knuckles — a noticeable difference on impact.
Most brands offer 10, 12, 14 and 16 oz. Some go down to 8 oz for speed work, and up to 18 or even 20 oz for larger frames or maximum protection in sparring. 10 oz is the size used by most professionals in competition; 16 oz is the reference for sparring.
Wraps and glove care
Hand wraps are essential under gloves, without exception. They hold the carpal bones and the wrist together through repeated impact. Choose elastic cotton wraps to avoid irritating the skin. See our hand wrap collection to find the length and type that suit you.
To care for gloves after each session, let them dry in open air with the closure loosened and the opening facing up, never sealed in a bag. Use a disinfectant spray or cedar deodorising inserts. For the full method, see our complete guide to glove care.

Frequently asked questions about glove sizes
Is there a difference between men's and women's gloves?
No, boxing gloves are unisex. Size depends only on body weight and use — training, sparring or competition. Women follow the same sizing guide as men for their weight.
Why are boxing gloves measured in ounces?
Historically, gloves were padded with horsehair and manufacturers weighed them to guarantee a uniform level of protection. That ounce system became the world standard and has persisted even though gloves are now made with synthetic foam.
Do you always have to wear wraps under gloves?
Yes, without exception. Wraps hold the carpal bones, the tendons and the wrist through repeated impact. Without them, even in good gloves, you risk long-term joint injury.
What glove size for sparring?
For sparring, always go one size up from your usual training size. The extra padding protects your partner during hard exchanges. Most clubs require 14 oz minimum, and 16 oz for frames over 80 kg (175 lb).
How long does a pair of boxing gloves last?
In PU with three sessions a week and good care: 1 to 2 years. In genuine leather, well maintained: 3 to 5 years. The first signs of wear are the padding losing its shape and the stitching starting to open.
What glove size for an 8-year-old?
For a child of roughly 7 to 12, 8 oz gloves are appropriate. For younger children of 5 to 7, 6 oz suits better. Children's gloves are sized differently from adults': here the ounce corresponds more directly to the physical size of the glove.
