How to Choose the Right Boxing Gloves: Size, Type & Material Explained

Choosing the right pair of boxing gloves comes down to one number: ounces (oz). That's exactly what this boxing gloves size guide is here to help you nail down, how much padding sits between your hands and every punch you throw, and why that affects your protection, your comfort, and how long your gloves last.

This guide breaks down boxing glove sizing by weight, hand circumference, and training style, with a full size chart you can check in seconds. We'll also cover something most sizing guides skip: how Muay Thai gloves differ from Western boxing gloves, and why that matters if you train in both.

Boxing Gloves Size Guide: Size Chart

Boxing glove weight is measured in ounces (oz), not S/M/L. The right oz for you depends on body weight, hand circumference, and what you're training for.

Glove Weight	Body Weight (lbs)	Body Weight (kg)	Hand Circumference (in)	Best For
8 oz	Up to 110 lbs	Up to 50 kg	5" – 6"	Competition, speed work
10 oz	110 – 130 lbs	50 – 59 kg	6" – 6.5"	Bag/pad work, smaller hands
12 oz	130 – 150 lbs	59 – 68 kg	6.5" – 7"	All-purpose training
14 oz	150 – 175 lbs	68 – 79 kg	7" – 7.5"	Sparring, mixed training
16 oz	175 – 200 lbs	79 – 90 kg	7.5" – 8.5"	Sparring, max protection
18 oz	Over 200 lbs	Over 90 kg	8.5"+	Heavy sparring, larger hands

General guidelines only: always try gloves on with hand wraps for the most accurate fit. YOKKAO covers the full 8oz–18oz range, so you can size up or down without switching brands as your training changes.

How to Measure Your Hand Size for Boxing Gloves

If your body weight falls between two sizes, hand circumference is the tiebreaker.

Wrap a flexible tape measure (or string and a ruler) around your dominant hand, just below the knuckles.
Keep the tape centered across your palm for an accurate reading.
Match the measurement to the chart above.

Pro tip: Measure with your hand wraps on if you plan to train in them, it gives a truer sense of your actual in-glove fit.

Boxing Gloves Size Guide by Oz: What Each Weight Is For

8oz - Competition & speed work:

Lace-up gloves for official bouts and light pad/bag training. Best for fighters around 80–110lbs. Not suitable for sparring, too little padding to protect a partner.

10oz - Training & competition:

A touch more padding than 8oz, good for bag and pad work. Suits fighters roughly 110–143lbs. Still too light for regular sparring.

12oz - All-purpose training:

The best "first glove”, balances protection and speed for fighters around 132–165lbs. Not ideal for hard sparring.

14oz - Sparring & mixed training:

Enough protection for partner safety, plus bag and pad work. Suits fighters over 154lbs, who want one glove for everything.

16oz - Maximum protection for sparring:

The standard for full-contact sparring and conditioning, for fighters around 143–176lbs+.

18oz - Heavy sparring & larger hands:

Extra cushioning for fighters over 200lbs or anyone doing long, high-volume sparring sessions.

Boxing Gloves vs. Muay Thai Gloves: Does Size Differ?

Most sizing guides skip this, because most brands only sell for one sport.

Boxing and Muay Thai gloves are sized the same way, by weight in ounces, but built differently, which changes how a given oz feels:

Wrist support:

Boxing gloves use a longer, stiffer cuff for straight-punch stability. Muay Thai gloves are shorter and more flexible to allow clinching, elbows, and rotational striking.
Palm shape:

Muay Thai gloves are curved with a more open palm for catching kicks and gripping, something standard boxing gloves aren't built for.
Padding:

Boxing gloves concentrate padding at the knuckle; Muay Thai gloves often add extra padding at the palm base for blocking.

For sizing: the same oz gets you comparable protection across both disciplines, expect the fit and movement to differ, not the number. Rodtang, Superlek, and Saenchai train in YOKKAO gloves daily across both boxing and Muay Thai sessions, which is exactly why the brand builds for both from day one instead of adapting a boxing-only design.

Boxing Glove Sizing for Men, Women & Youth

Sizing is based on body weight and hand circumference, not gender.

By fighter type:

Men & women:

Same oz range applies to both, a 130lb man and a 130lb woman with similar hand size land in the same size.
Youth & smaller-handed fighters

Typically start at 8–10oz.
Beginners:

training for fitness or technique: Usually do well in 12–14oz.

Choosing between sizes:

Prioritize hand circumference over body weight, a snug fit protects your wrist and knuckles more than sheer padding.

Boxing Glove Material and Construction

Material doesn't change your oz sizing, but it affects break-in time and long-term fit. At YOKKAO, every pair uses 100% genuine cowhide leather or A-grade microfiber, not the synthetic leather many brands use at the same price point.

Premium Leather:

genuine cowhide leather, chosen for superior durability, breathability, and the way it molds to your hand over time. The same leather YOKKAO's fighters train daily.

Microfiber Leather:

A-grade microfiber engineered to maintain shape, structure, and protective performance through daily use, at a more accessible price point. Lightweight, water-repellent, fast-drying, ideal for beginners and everyday gym use.

Does Glove Weight Affect Punching Power?

No. Heavier gloves add padding, not power, they protect your hands and your sparring partner, nothing more. Punching power comes from technique, weight transfer, and speed. This is why competition gloves stay light (8–10oz) to let skill show through, while sparring gloves go heavier (16–18oz) purely for protection during sustained contact.

How do I choose between different glove weights (8oz–18oz)?

Lighter gloves (8–10oz) suit competition and speed work. 12oz is the best all-purpose choice for training. 14–16oz is standard once you're sparring regularly. 18oz adds extra cushioning for larger fighters or long, high-volume sparring sessions.

What size boxing gloves do you use?

Start with the chart above based on your weight and hand circumference, then confirm with the measuring method if you're between sizes.

Which glove size is best for beginners?

Most beginners do well in 12–14oz, enough padding to be forgiving while you build technique, without feeling bulky. Training for fitness rather than sparring, 12oz is usually the comfortable start.

Can I use the same gloves for sparring and bag work?

It's possible, but not ideal. Bag gloves carry less padding for heavy-bag impact; sparring needs extra padding to protect your partner. If you can only own one pair, lean toward sparring gloves (14–16oz) for more overall protection.
