Glove size in boxing is measured in ounces (oz), which tells you how much padding you’re working with. The “right” size depends on your bodyweight and what you’re doing: bag work, pad work, or sparring. Use this guide to pick a safe, comfortable glove that lets you throw clean 1–2–3–4–5–6 without wrecking your hands or your partner.
Browse coachesBoxing glove “size” is measured in ounces, which is the weight of the glove and padding, not how hard it hits. Lighter gloves (8–10 oz) have less padding and feel faster, while heavier gloves (14–18 oz) have more padding and protect your hands and training partner better. Most adults train in 12–16 oz gloves. Beginners should ignore pro fight gloves for now and pick a training glove weight that matches their bodyweight and the type of work they’ll do most: bag, pads, or sparring.
Use your bodyweight as a starting point, then adjust for comfort and hand size. For bag and pad work only, many adults can go slightly lighter; for sparring, go heavier for safety. A simple guide: under 120 lb (54 kg): 10–12 oz, 120–150 lb (54–68 kg): 12–14 oz, 150–180 lb (68–82 kg): 14–16 oz, 180+ lb (82+ kg): 16–18 oz. If you’re unsure and just starting, 12–14 oz is a safe all‑round choice for most beginners.
On the heavy bag and mitts, your priority is protecting your hands and wrists while throwing lots of 1–2s, 1–2–3s, and 1–2–3–6s. You can usually go a bit lighter than your sparring gloves so the rounds feel snappier. For most adults: under 100 lb: 6–8 oz, 100–125 lb: 10 oz, 125–150 lb: 12 oz, 150–175 lb: 14 oz, 175+ lb: 16 oz on the bag. If your knuckles or wrists feel beat up, move up an ounce size or two for more padding.
For sparring, boxers generally go up one glove size (about 2 oz) from their bag‑work gloves for extra padding and safety. Many gyms standardize on 16 oz gloves for adult sparring, especially once both boxers are over about 150 lb. Lighter boxers under ~130 lb may spar in 14 oz if the coach approves. More padding softens your 1–2–3–4 combinations and reduces cuts and bruises. Always ask your coach what the gym rule is before buying sparring gloves.
Kids need lighter gloves that still protect growing hands. A simple youth guide: ages 3–6: 4–6 oz, 7–9: 6–8 oz, 10–12: 8–10 oz, 13–15: 10–12 oz. Bodyweight matters too: under 100 lb is usually 8–10 oz. Always prioritise control and proper technique on basic 1–2s over power. Gloves should be snug with wraps on, but not painful or cutting off circulation. When in doubt, check the gym’s policy and try gloves on in person if possible.
Measure around your knuckles (no thumb) and use the brand’s size chart to pick hand size, then choose glove ounces from this guide. Wrap your hands fully, put the gloves on, and make a real fist like you’re about to throw a 2 or 6. Your fingers should reach near the top without feeling jammed, and the wrist strap should lock the glove without cutting into your skin. If you can’t close a fist, or your hand slides around when throwing 1–2–3, the glove doesn’t fit right.
Many beginners buy gloves that are too light because they feel fast, then end up with sore hands from smashing the bag with hard 2s and 4s. Others go way too big, making it hard to feel their shots and learn clean 1–2–3–6 technique. Another mistake is ignoring hand wraps; gloves are designed to be worn with wraps, and fit changes a lot without them. Finally, people often skip asking their coach, then find out their gym requires 16 oz for sparring and have to buy twice.
Both 12 oz and 14 oz can work for beginners; under about 150 lb, 12 oz is usually fine for bag and pad work, while 14 oz adds a bit more padding. If you plan to spar soon or want extra protection as you learn your 1–2–3, 14 oz is the safer bet, but always check your coach’s recommendation.
Ideally, yes: one pair slightly lighter for bag/pad work and a heavier, well‑padded pair for sparring. For example, you might use 12–14 oz on the bag for sharp 1–2–3–2s, and 16 oz for sparring so your shots land softer on your partner.
Most gyms don’t allow 12 oz gloves for sparring because there isn’t enough padding to protect your partner. Unless you are very light and your coach specifically says it’s okay, plan on at least 14 oz, with 16 oz being the standard for adult sparring.
Heavier gloves don’t make you hit harder; they add padding and slow your hand slightly, which can actually be good for building shoulder endurance on long 1–2–3–4 combinations. What increases power is technique, timing, and proper mechanics, not glove weight.
Gloves should feel snug with wraps on: your hand shouldn’t slide, and you should be able to make a firm fist comfortably. If your fingers are jammed, your thumb feels twisted, or the strap digs in when you throw a hard 2, the glove is too small or the wrong shape for your hand.
