About this site

One tool that answers one question: how many boxes do you actually need to move? No quotes, no lead forms, no phone number to give up first.

Why it exists

Every box retailer sells a "moving kit" sized by bedroom count, and most of them oversell it, because a bigger kit is a bigger order. This site does the sizing honestly instead: tell it your home size, how much you've accumulated, and how long you've lived there, and it gives you a count broken down by box size, not just a total you have to guess how to split.

The split is the part that actually matters at the store. Buying the wrong ratio of small to medium means a second trip mid-pack for whichever size runs out first, and that's the mistake this tool is built to prevent.

Where the numbers come from

Box counts are calibrated against the ranges the major retailers and moving companies themselves publish for each home size, then split by box size using the same reasoning a mover uses: heavy and dense goes in small boxes, bulky and light goes in large ones. The packing timeline works the same way — it's built from the box counts, not a separate guess.

Who makes it

FourFold Labs LLC, a small software company. Our other moving tool is whatsizestorage.com, which answers the storage-unit-size question instead of the box-count one — same underlying numbers, different question.

Get in touch

If a number here looks wrong, tell us and say why — that's the most useful mail we get. john@fourfoldlabs.com.

How this is paid for

Ads, and links to buy the boxes themselves, which earn us a commission when you use them. Those links are labelled where they appear. Nothing about that changes what the tool tells you — the count comes from your answers, not from what's for sale.
