Underestimating how many boxes a move requires means an inconvenient extra supply run mid-packing, while overestimating wastes money on unused boxes — this calculator gives a reasonable starting estimate based on typical home sizes.
Select your home size, and the tool returns a breakdown by box size (small, medium, large) based on commonly cited moving industry estimates, along with a total count to guide your box purchase or rental.
These are general estimates assuming a typically furnished home — a minimalist household will need fewer boxes, while a home with an especially large book or media collection may need more small boxes specifically, since heavy items pack better in smaller boxes.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.

Frequently asked questions
Why are there more small boxes than large boxes in the estimate?
Small boxes are recommended for heavy items like books, since a large box full of heavy items becomes difficult and potentially unsafe to lift, so the box mix skews toward smaller sizes for practical weight distribution.
Should I buy extra boxes beyond this estimate?
It's generally wise to have a few extra of each size on hand, since packing always seems to require slightly more boxes than initially estimated.
