How Big a Tennis Bag Do You Need for Practice?
Choose a tennis bag that holds your rackets and usual court gear without becoming awkward on the way there.

Pack everything you take to a typical session on a table. Count the rackets, then add the water bottle, balls, towel, shoes and anything you need after playing. Most bag capacity labels emphasize racket count. They give you less information about the shape and access of the compartments.

Check the racket compartment first
Make sure it closes with the racket you actually carry. If it’s a backpack with exposed handles, see whether they swing into your head or catch on a doorway. Check how the racket shares space with shoes and clothes when the main compartment is full.
Give wet and clean gear different places
A removable bag can work for damp clothes if you want to wash it separately. Keep a leaky drink bottle away from grips and electronics. Check the shoe pocket with the pair you wear, since filling it can reduce space in the next compartment.
Test the commute
Load the bag and walk a short distance before deciding. Check the straps with the heaviest setup you routinely carry. If you travel to the court by bike or public transit, a compact bag that stays close to your body may be easier to manage than a larger racket bag.
