Guide to OZ and boxing glove sizing

How to choose the right size of boxing gloves – a simple guide for beginners

When you buy boxing gloves for the first time, you will quickly come across the word "OZ" . This stands for ounces, an international unit of weight.

• 1 oz = about 28 grams

• The lower the oz, the lighter the glove

• Boxing gloves are usually available from 4 oz to 20 oz.

A lighter glove allows for faster movements, while a heavier glove provides more protection – and a heavier workout for the arms and shoulders.

Which weight should you choose?

Fight (World boxing and IBA rules):

• Under 64 kg → 10 oz

• 69 kg and above → 12 oz

Training/sparring:

• Move up one weight class from the fighting rules for better protection

• Over 80 kg → choose 16 oz for sparring

Bag and fitness gloves:

• Choose according to comfort and fitness goals

• 10–12 oz is great for backpacks, pillows and fitness

Light vs. heavy gloves

Lightweight gloves (4–10 oz):

• Faster strokes and better flow

• Less protection – not recommended for sparring

Heavy gloves (12–20 oz):

• More resistance, better strength and conditioning training

• Provides better safety for both you and your opponent

Recommended size

• Children 5–12 years: 4–10 oz for technique and light bag training

• Youth from about 12 years: 12–14 oz for sparring

• Adults under 64 kg: 12–14 oz for sparring

• Adults 64–80 kg: 14–16 oz for sparring

• Adults over 80 kg: 16 oz for sparring

• All: 10–12 oz for bag and fitness

Why youth should use heavier gloves in sparring

Even though youth weigh less, the blows can still be hard enough to cause injury. Therefore, 12–14 oz is recommended for sparring:

• More padding reduces impact force

• Better protection of hands and wrists

• Safer training with less risk of injury

Boxing gloves for children

• Typically 4–8 oz for technique and light bag training

• The glove should fit snugly, but not tight.

• Always use boxing bandages

Why boxing bandages are important

Bandage protects wrists, knuckles and small joints.

• Adults: 4–5 m bandage

• Children: 2.5–3 m bandage

Tips before choosing a glove

• Think about the purpose: fighting, sparring, punching bag or fitness

• Feel free to try several sizes

• Many people who exercise a lot have multiple gloves for different purposes.

• Remember: boxing bandages are just as important as the gloves themselves

💡 Conclusion:
There is no one perfect glove for everyone. Choose a glove based on weight, application, and safety. With the right fit, padding, and bandage, you are ready for safe and effective training.
