The weight of boxing gloves for sparring depends on the boxers weight and the type of boxing they intend to do. Generally, boxing glove sizes are measured by weight, using ounces, not size. The standard boxing glove weights are 12, 14, and 16 ounces. Here are some basic sizing information based on boxer weight class:

• Under 100 lbs (including children): 6-8 oz boxing gloves
• 100-125 lbs: 10 oz boxing gloves
• 125-150 lbs: 12 oz boxing gloves
• 150-175 lbs: 14 oz boxing gloves
• 175+ lbs: 16 oz boxing gloves

Most amateurs will use 16 oz gloves for sparring and bag work. However, if you are a really small person, you could train with 14 oz gloves. Heavyweight boxers may use 20 oz gloves. It is recommended to use separate gloves for sparring to avoid pounding down the foam on the gloves.
