To check whether a tennis bag will fit in a locker, compare three things: the clear door opening, the usable space inside, and the outside shape of your packed bag, including any racquet handles. A litre figure alone cannot answer this question. Use the same units for every measurement and check the orientation you intend to use.
This guide gives you a small measurement card to take to your club. For a two-racquet tote, the Westmount Tennis Weekender has published dimensions of 40 × 16 × 39 cm, length × depth × height. Start with that outline, then compare your own packed arrangement.

Check the opening before the interior
With permission from the club, measure the clear width and height of the open doorway. Look at the space the bag must pass through, not the width of the full locker cabinet. A door frame or hinge can affect that route.
Next, measure the usable space inside. Include depth with the door closed. Note any shelf, rail or hook that changes the space available for your bag. A tall compartment with a fixed shelf is a different storage arrangement from an unobstructed compartment of the same overall height.
| Check | Write down | Compare against |
|---|---|---|
| Entry | Clear opening width and height | The bag's profile as it passes through the doorway |
| Interior | Usable width, height and depth; position of shelves and hooks | The space occupied by the packed bag in its resting position |
| Closure | The path and final position of the door | Handles, straps, racquets and other items outside the bag body |
Measure the bag you will actually bring
Pack your usual kit and close the bag as you normally would. Measure its widest, deepest and tallest points in that state. Include anything that projects beyond the bag body, particularly racquet handles. Keep a note of the orientation: upright and on its side give you different profiles to compare.
If your club permits a trial, place the bag inside without forcing it or pressing the racquet against the door. Check that the door closes freely and that the contents remain in the arrangement you intended. Bring the straps inside before closing. This is a practical fit check for that locker and that load, rather than a promise about every locker in the club.
Use the Westmount's outline as your starting point
The Westmount combines a 25-litre tote body with a dedicated exterior pocket for up to two racquets and a separate side shoe compartment. Its published 40 × 16 × 39 cm dimensions give you a clear starting outline. The packed measurement card then accounts for the items you choose to carry.
For the separate question of how much kit you need to carry, use our tennis bag size guide. This locker check concerns access and storage space once you arrive.
Confirm the club's arrangement
Ask which lockers your booking or membership includes, whether you need your own lock, and when belongings must be removed. Facilities describe their own arrangements: for example, Toronto's Mayfair Clubs amenities page lists day lockers among its complimentary services. Confirm the current details with the club you will visit.
Save the club name and locker location with your measurements. That makes the note useful on your next visit, especially when a facility has more than one type of locker.
For an understated tote with a clear published outline and dedicated court compartments, explore the Westmount Tennis Weekender. Its handles and adjustable, detachable crossbody strap give you carrying options from the changing room to the rest of your day.
