Container Fit overview
Moving Box
A cardboard carton has a fixed interior, so only small items and tightly packed goods fit inside.
Moving Box
Typical Measurements
Medium box
18 x 18 x 16 in
Small box
16 x 12 x 12 in
Large box
18 x 18 x 24 in
Top flap opening
Full top (box width x depth)
These are planning defaults. Measure your real opening before buying, moving, or booking delivery.
Fit Notes
- Full top-flap opening means interior dimensions are the only constraint.
- Heavy items go in small boxes; large boxes are for light, bulky goods.
- Leave the flaps able to close flat; overpacked boxes will not stack.
