Toy Box and Toy Chest Dimensions: Sizes, Capacity and Safe Lids
For parents choosing toy storage and for anyone building a toy chest. Toy boxes have no standard size, so the useful numbers are capacity, seat height if it doubles as a bench, and the lid rules that keep it safe.
A typical toy box is about 30 in wide, 15 in deep and 18 in tall (76 × 38 × 46 cm), which holds about 4.7 cu ft (133 L) measured outside. Small chests are about 24 × 13 × 14 in (61 × 33 × 36 cm) and large ones about 36 × 18 × 20 in (91 × 46 × 51 cm). Any lid should stay open in any position and never latch.

Standard toy box sizes
Sizes below are outside dimensions, width × depth × height with the lid closed. Capacity is the outside volume; a wooden chest with ¾ in (19 mm) walls holds about three-quarters of that inside.
| Size | Inches (W × D × H) | Centimeters | Capacity |
|---|---|---|---|
| Small | 24 × 13 × 14 | 61 × 33 × 36 | 2.5 cu ft (72 L) |
| Standard | 30 × 15 × 18 | 76 × 38 × 46 | 4.7 cu ft (133 L) |
| Large | 36 × 18 × 20 | 91 × 46 × 51 | 7.5 cu ft (212 L) |
| Extra large | 42 × 20 × 22 | 107 × 51 × 56 | 10.7 cu ft (303 L) |
| Kids' bench chest | 30 × 14 × 13 | 76 × 36 × 33 | 3.2 cu ft (89 L) |
| Adult-height bench chest | 36 × 15 × 17 | 91 × 38 × 43 | 5.3 cu ft (150 L) |
| Collapsible fabric chest | 24 × 12 × 12 | 61 × 30 × 30 | 2 cu ft (57 L) |
Doubling each dimension multiplies the capacity by eight, which is why a large chest holds about three times as much as a small one while looking only a little bigger. If the box will sit at the foot of a bed, match its width to the bed: 30 in suits a crib or toddler bed frame, and 36 in a twin.
How big a toy box you need
Gather the toys that will go in it and pile them into laundry baskets. A standard 1.5-bushel laundry basket holds about 1.9 cu ft (53 L). Then add a third for growth and so the box can close without pressing down on the lid.
- 1 basket of toys: small chest, about 2.5 cu ft.
- 2 baskets: standard chest, about 4.7 cu ft.
- 3-4 baskets: large or extra-large chest, 7.5-10.7 cu ft, or two standard boxes.
Bigger is not always better. A child of 2 to 4 has an arm about 13-16 in (33-41 cm) long from shoulder to fingertip, so toys at the bottom of a 20 in chest are hard to reach and get forgotten. Boxes 14-16 in tall suit toddlers and preschoolers. For large collections, several shallow containers work better than one deep chest.
Lids, frames and thick walls take a lot of space. A chest listed as 30 × 15 × 18 in may have an interior of 28.5 × 13.5 × 15.5 in, about 3.5 cu ft. For long toys, compare their length with the interior width.
Toy chest benches: seat height and depth
A chest with a flat, padded lid doubles as a seat. Who sits on it decides its height.
| Who sits on it | Seat height | Seat depth |
|---|---|---|
| Toddlers (2-4 years) | 10 in (25 cm) | 12-14 in (30-36 cm) |
| Children (4-8 years) | 12-14 in (30-36 cm) | 13-15 in (33-38 cm) |
| Adults (entry or window seat) | 17-19 in (43-48 cm) | 15-18 in (38-46 cm) |
The seat heights match the chair heights in the kids' furniture guide. A bench lid gets sat and stood on, so it should be at least ¾ in (19 mm) plywood or solid wood, and its hinges must still meet the lid rules below. Benches with open cubbies or bins below, rather than a lift-up lid, avoid the lid hazard altogether.
Toy box lid safety
Children have died after a toy chest lid fell on their head or neck while they reached in, and after climbing inside a chest that latched or had no ventilation. The federal toy standard, ASTM F963, includes toy chest requirements, and the Consumer Product Safety Commission advises:
- A lid support that holds the lid open in any position, so it cannot drop when a child lets go. Spring-loaded or soft-close supports qualify; a plain hinge with a chain stay does not.
- No latch or lock that could trap a child inside.
- Ventilation, through holes or a gap under the lid, that stays open when the chest is pushed against a wall or set on carpet.
- No lid at all is the simplest option for toddlers, or a removable lid that lifts off fully.
Hope chests, blanket chests and second-hand toy boxes made before current rules often have heavy lids with no support. Fit a lid support rated for the lid's weight, or remove the lid, before a child uses one.
Bins, cubes and other toy storage sizes
Open storage is easier for small children to use and tidy, and it fits standard furniture.
| Container | Inches | Centimeters | Volume |
|---|---|---|---|
| Fabric cube bin, 11 in system | About 10.5 × 10.5 × 11 | About 27 × 27 × 28 | About 20 L |
| Cube bin for 13 in shelving (KALLAX-type) | About 13 × 15 × 13 | 33 × 38 × 33 | About 41 L |
| TROFAST shallow box | 16.5 × 11.8 × 3.9 | 42 × 30 × 10 | 12.6 L |
| TROFAST medium box | 16.5 × 11.8 × 9.1 | 42 × 30 × 23 | 28.8 L |
| Under-bed box | 30-40 × 16-18 × 6 | 76-102 × 41-46 × 15 | 40-70 L |
| Rolling toy cart (3 drawers) | 16 × 13 × 25 | 41 × 33 × 64 | About 85 L outside |
IKEA's KALLAX shelving has 33 × 33 cm (13 × 13 in) compartments, and many other brands use about 11 in cubes. Bins from one system do not fit the other, so measure the opening before buying. Under-bed boxes need the clearance under the frame: about 7 in or more for a 6 in box. For closet systems and larger units, see closet organizer sizes and storage unit sizes.
Building a toy chest: working dimensions
For a DIY chest in ¾ in (19 mm) plywood, start from the inside size you need and add the material.
- Width and depth: add 1.5 in (38 mm) for two walls. An interior of 28.5 × 13.5 in gives an outside of 30 × 15 in.
- Height: add the bottom panel (¾ in), any base or feet (0.5-2 in) and the lid (¾ in). An 18 in chest with a 1 in base leaves about 15.5 in of interior depth.
- Lid: overhang the box by ¼-½ in on the front and sides, and leave a finger gap at the back hinge line or fit a hinge designed to avoid pinching.
- Hardware: choose the lid support by lid weight. A 30 × 15 in lid in ¾ in plywood weighs about 6-8 lb (2.7-3.6 kg).
- Handles: cut hand holes at the ends, about 1 × 4 in, which also act as ventilation.
A chest built to these sizes sits comfortably beside a play kitchen or under a window, and a low one makes a stand for a small dollhouse.
Frequently asked questions
What are the measurements for a toy chest?
Most toy chests are 24-36 in (61-91 cm) wide, 13-18 in (33-46 cm) deep and 14-20 in (36-51 cm) tall. The most common size is about 30 × 15 × 18 in. Bench-style chests designed for adults to sit on are 16-18 in tall to the seat.
What size toy box is good for a girl's or boy's room?
The size depends on the toys and the room, not the child. For a bedroom, a chest of about 30 × 15 × 18 in fits at the foot of a twin or toddler bed and holds a typical collection of soft toys and larger plastic toys. For a young child, a lower box of 14-16 in lets them reach the bottom.
How much does a toy box hold?
A 30 × 15 × 18 in box is 4.7 cu ft (133 L) outside and about 3.5-4 cu ft (100-110 L) inside for a wood chest with ¾ in walls. That is two to three full laundry baskets of loose toys.
What size is a toy box for an 18-inch doll or a large plush?
An 18 in (46 cm) doll or plush needs an interior of at least 19-20 in in one direction, so choose a chest at least 24 in wide on the outside. Long items such as toy swords, wands and play tunnels need a 30-36 in chest.
