Boxing glove sizes are not standard 2

Q..Aren't size and weight of glove the same thing?

A..No. Glove size and glove weight are not the same thing. In some cases the sizing can correspond with the weight of a glove, but many times it is not true.

At a glance, boxing gloves all look the same. While the weight of boxing gloves may be the same, their actual "Hand Compartment"sizes differ. Boxing gloves are made with a Hand Compartment called the "hand cage". This is the portion of the glove that directly cradles your fist. Boxing gloves come in a variety of weights, ranging from 8 oz. to 20 oz. The larger the weight,the more padding on the glove, so larger weight dose not really effect the hand cage size. Machina Carbonado gloves and Hayabusa Tokushu Plus gloves both come in 16 oz. The thing is, my hands with wraps on won't fit well into a pair of Machina 16 oz gloves. Their hand cages are more narrow and shallow than a traditional boxing glove. So Hayabusa Tokushu Plus 16 oz gloves have the same weight as Machina gloves but will appear larger and bulkier.

Hand Compartment/hand cage sizes differ across brands.
 
Different people have different needs. There are brands which specialize in a certain area, some offer more protection than others. Just because a glove is more popular does not mean the glove is the best fit for you. Brands like Everlast, Revegear and Windy, all have big hand cages, while brands like Twins, Society Nine, and Danger, have smaller hand cages. To know the right size for you. Test my statements. Go to a real boxing gym and try on different types and brands of boxing gloves they have. Check out the shape, padding, and comfort. Then just go home and order the brand that fits you well online.
