Choosing the wrong size boxing gloves is one of the most common mistakes beginners make. Too light and you risk injury. Too heavy and your technique suffers. The right size depends on your body weight, what you are training for, and whether you plan to spar.
This guide covers everything you need to know about boxing glove sizing in the UK: what the oz weight means, which size suits your weight and training style, and which gloves are worth buying.
What Does the Oz Weight Mean?
Boxing gloves are sized in ounces (oz), which refers to the weight of the glove, not the size of your hand. Heavier gloves have more padding. More padding means more protection for your hands and your training partners during sparring.
The oz weight does not change based on your hand size. A fighter with large hands and a fighter with small hands both wear 16oz gloves for sparring. Hand size affects the fit inside the glove, not the oz weight you choose.
Boxing Glove Size Chart UK
| Oz Weight | Body Weight | Best For |
|---|---|---|
| 8oz | Any | Competition only. Never train in these. |
| 10oz | Under 60kg | Bag and pad work only. Not for sparring. |
| 12oz | 60 to 70kg | Bag work and light sparring for lighter fighters. |
| 14oz | 65 to 80kg | Bag work, pads, and sparring. The sweet spot for most regular trainers. |
| 16oz | 75kg and above | Maximum protection. Standard sparring glove for most UK gyms. |
| 18oz | 90kg and above | Heavy sparring for larger fighters. Rarely needed. |
Which Size Should a Beginner Choose?
If you are just starting out, go with 16oz. Here is why:
- 16oz is the standard sparring weight in most UK gyms. You will not need to buy a second pair when you start sparring.
- The extra padding protects your hands during bag work while your technique is still developing.
- 16oz gloves are safer for your training partners during sparring.
- They work for bag work, pad work, and sparring. One pair does everything.
The only reason to start with 14oz is if you are a lighter fighter under 65kg who does not plan to spar, or if your gym specifically recommends 14oz for beginners.

14oz vs 16oz: Which Should You Choose?
This is the most common sizing question from intermediate boxers. Here is the honest breakdown:
Choose 14oz if:
- You weigh under 75kg
- You train primarily on pads and bags rather than sparring
- You want a faster, lighter feel during combinations
- Your gym allows 14oz for sparring
Choose 16oz if:
- You weigh over 75kg
- You spar regularly
- You are a beginner who wants one pair that does everything
- Your gym requires 16oz for sparring (most do)

Does Hand Size Affect Which Gloves I Buy?
Hand size affects the fit inside the glove but not the oz weight you choose. Most boxing gloves are designed to fit a range of hand sizes. Here is what to check:
- Finger length: Your fingers should reach the top of the glove without straining. If your fingers are cramped, the glove is too small internally.
- Thumb position: Your thumb should sit securely in the thumb compartment without being forced into an awkward position.
- Overall fit: The glove should feel snug but not tight. Always try gloves on with hand wraps as the wraps add significant bulk.
If you have particularly large hands, some brands offer wide-fit gloves. Check the specific product description for fit guidance.
What Size Gloves for Bag Work Only?
If you are training on the heavy bag only and not sparring, you have more flexibility on size. 12oz or 14oz gloves work well for bag work for most fighters. The lighter weight allows faster combinations and reduces arm fatigue during long bag sessions.
However, if there is any chance you will spar in the future, buy 14oz or 16oz from the start. You will not need to buy a second pair.
What Size Gloves for Muay Thai?
The same sizing guide applies to Muay Thai. 14oz or 16oz for sparring, 12oz or 14oz for bag and pad work only. Muay Thai gloves have a slightly different design with a more open palm for clinch work, but the oz sizing works the same way.

What Size Gloves for Kids?
Children need lighter gloves sized for smaller hands and developing wrists. Adult gloves are too heavy and too large for children under 12.
The Warriors Mindset Kids Boxing Gloves 4oz are made from real leather for ages 4 to 6, lightweight and safe for beginner boxing and Muay Thai training.
Do I Need Hand Wraps with My Gloves?
Yes, always. Hand wraps protect the small bones in your hand and stabilise your wrist before the glove adds its outer layer of protection. Never train without them, regardless of glove size.

Frequently Asked Questions
What oz gloves do professional boxers use?
Professional boxers compete in 8oz or 10oz gloves depending on weight class. These are competition gloves with minimal padding. They are not suitable for training. Never train in competition gloves.
Can I use 16oz gloves for bag work?
Yes. 16oz gloves work perfectly well for bag work. They are slightly heavier than 12oz or 14oz gloves which adds some arm fatigue during long sessions, but the extra padding is beneficial while your technique is developing.
What size gloves do I need for sparring?
Most UK gyms require 16oz for sparring. Some allow 14oz for lighter fighters. Check with your gym before buying. When in doubt, go with 16oz.
Are bigger gloves better for beginners?
Yes. More padding means more protection for your hands and your training partners. Beginners benefit from the extra protection of 14oz or 16oz gloves while their technique is developing.
How do I know if boxing gloves fit properly?
Try them on with hand wraps. Your fingers should reach the top of the glove without straining. The glove should feel snug but not tight. Your thumb should sit securely in its compartment. Close your hand into a fist. The fit should feel natural and secure.
