Moving & storage estimate

Review the example assumptions, enter your values and calculate.

How many moving boxes do I need?

For each box size, sum room count × boxes per room, multiply by (1 + extra allowance/100), then round upward. Total is the sum of the three rounded sizes.

Worked example

Two bedrooms at 4 small, 6 medium and 2 large boxes each, plus one kitchen at 8/4/2 and one living or other room at 2/4/2, with 10% extra, need 20 small, 22 medium and 9 large boxes: 51 total.

Assumptions & limitations

  • Room assumptions are illustrative, not a surveyed household average. Edit them to match your belongings; avoid counting rooms twice.
  • Box size names have no universal dimensions. Use your supplier’s dimensions and weight ratings. Heavy items usually need smaller boxes. Furniture and unpacked items are excluded.
