How to Choose the Right Storage Unit Size

The right unit is large enough to load safely and small enough that you are not paying for unused floor. A quick inventory is more useful than guessing from room count alone.

Start with a simple inventory

List large furniture first, then estimate the number of medium boxes. Note anything unusually long, fragile, or difficult to stack. Measurements matter most for wardrobes, sofas, mattresses, shelving, and business equipment.

Use familiar room comparisons

A 5 x 5 ft unit is similar to a generous closet. A 5 x 10 ft unit can hold the contents of a compact apartment when packed well. A 10 x 10 ft unit gives about 100 square feet and works for several rooms of furniture and boxes.

Decide how often you will visit

If everything is staying until one final move-out, tight packing may be sensible. If you need weekly access, allow an aisle and keep active boxes near the door. Easy access can make a slightly larger unit the better fit.

Account for packing quality

Uniform boxes stack more efficiently than bags. Disassembled furniture uses less floor area, but only when parts are protected and hardware is labeled. Never stack heavy boxes on fragile furniture.

Ask for a second opinion

Share photos, a room list, or rough dimensions with the Cornerkeep team. We can compare two realistic options and explain the trade-off before you reserve.
