Whether it fits comes down to the measurements most people skip.

What to measureMeasure sofas, mattresses, dressers, tables, appliances, and box counts

Real openings run about 1 to 2 inches under the labeled size, and a single inch can flip the result. Check your own measurements before you buy or move.

Measure smart

What to measure.

Four numbers decide nearly every fit check. Get these right and the rest follows.

  1. 01Furniture list with dimensions for sofas, mattresses, dressers, tables, shelves, and appliances
  2. 02Box count by size and whether boxes can stack safely
  3. 03Largest rigid item compared with storage unit door opening and aisle clearance
  4. 04Access aisle needs if you will retrieve items before moving everything out

Don't make these

Common mistakes.

Most “it didn't fit” stories trace back to one of these oversights.

  1. ⚠Choosing by square footage only and ignoring height, door opening, and aisle plan
  2. ⚠Forgetting that mattresses, upholstered furniture, TVs, and glass should not be stacked under heavy boxes
  3. ⚠Renting a 5x10 for a full one-bedroom load with bulky furniture, then running out of floor space
  4. ⚠Not measuring the storage unit roll-up door, which can be narrower or shorter than the interior unit

Frequently asked

Questions we keep getting.

  • What size storage unit do I need for a one-bedroom apartment?

    A 10x10 unit is the common starting point for a one-bedroom apartment with a sofa, bed, dresser, small table, and boxes. A minimal one-bedroom can fit in 5x10, but bulky furniture usually pushes the load to 10x10.

    01
  • What fits in a 5x10 storage unit?

    A 5x10 unit can hold a mattress set, small sofa or loveseat, dresser, boxes, and a few small items. It is usually too tight for a full one-bedroom apartment with dining furniture and large appliances.

    02
  • What fits in a 10x10 storage unit?

    A 10x10 unit often fits the contents of a one-bedroom apartment: sofa, queen bed, dresser, table, chairs, and 20-30 boxes if packed carefully.
