What Does Oz Mean in Boxing Gloves?
The size of boxing gloves is measured in ounces (oz), which reflects the weight of the glove – not the hand size. The higher the oz, the more padding, which means more protection for you and your sparring partner.
Are Boxing Glove Sizes Universal?
Many assume glove size refers to hand size, like shoes or clothing, but that’s a myth. Oz only reflects glove weight and padding – not fit. Most adult boxing gloves are “one size fits all” internally.
Some brands like Hayabusa, Fairtex, or Twins may have a snugger or wider fit. These brands may also offer models specifically made for narrow or wider hands, such as women’s or youth-specific designs.
Boxing Glove Sizes Explained
- 6 oz:
Small gloves for very young children (around 6 years old). Lightweight yet protective for beginner training. - 8 oz:
Suitable for kids and teens. Occasionally used in amateur competitions. Too light for adult use. - 10 oz:
Common for adult competitions and bag/pad work. Less padding – not ideal for sparring. - 12 oz:
All-round gloves for training, bag work, and light sparring. Good balance between speed and protection. - 14 oz:
Great for general training and moderate sparring. Often the go-to size for adults. - 16 oz:
The preferred size for sparring due to extra padding. Often mandatory in gyms for safety reasons. Also useful for resistance training.
Boxing Gloves for Women
Women typically use the same oz sizes as men. The main difference is hand fit – women’s hands are often narrower, so choosing gloves with smaller internal dimensions or women-specific models is key. Popular choices: 12 oz for bag training and 14–16 oz for sparring.
Boxing Gloves for Kids
Kids need specially sized gloves due to their smaller hands and lower weight. Common sizes:
- 4–6 oz: young children (up to 6 years old)
- 8 oz: ages 6–10
- 10 oz: older kids and teens
This ensures safety without being too heavy or oversized.
Glove Differences by Sport
Different combat sports require different glove specs:
- Boxing: Typically 12 oz for training, 16 oz for sparring.
- Kickboxing / Muay Thai: Often 14–16 oz to handle kicks and clinching.
- MMA Training: 10–12 oz for bag work, 14–16 oz for sparring (see also: What is a weight class in kickboxing?)
Brand Fit Differences
Not all brands fit the same. Premium gloves like Hayabusa, Twins, or Fairtex may have denser padding or different cuts. A 14 oz glove from Fairtex might feel bulkier than a budget brand’s 14 oz.
