We pick it up, store it in Rockville and bring it back
Nothing to load yourself. Our climate-controlled warehouse is in Rockville, MD, you can visit it, there is no minimum period and partial months are prorated.
Monthly rates charged by the day, plus a one-time handling charge when it goes in; pickup and delivery are priced as a move. With a local move, the first month is free while space allows.
How it works
Start with the rooms every home has, add the ones yours has (basement, garage, attic), and tap each piece of furniture. Tap again for a second one. Search or use the A–Z filter for anything not in the room's list.
For every 200 lbs of furniture, the calculator adds the boxes a crew would pack: dishpacks, wardrobes, large, medium and small. Switch it off to add boxes by hand instead.
The calculator adds up the cubic feet, the way movers measure a load, and shows the smallest standard unit it fits in, how full it would be, and when the next size up is the comfortable choice.
By home
The usual answers, by home. Every home is furnished differently, so these are starting points; the calculator above gives you the size for your own furniture.
5×10 to 10×10
A studio with a bed, a sofa, a dresser and 15 to 20 boxes is around 300 to 400 cubic feet: a 5×10. A furnished 1 bedroom apartment with its kitchen comes to 500 to 800, which is a 10×10.
10×10 to 10×15
Two bedrooms of furniture, a living room set, a dining table and 40 or so boxes run 800 to 1,200 cubic feet. A 10×10 fits a lightly furnished one; a 10×15 leaves room to walk in.
10×15 to 10×20
Houses carry more: a garage, patio furniture, appliances. A 2 bedroom house usually fits a 10×15; a 3 bedroom house with everything in it is a 10×20, around 1,600 cubic feet.
10×20 to 10×30
Four bedrooms of furniture plus the rest of the house reach 2,000 cubic feet and more. A 10×30 holds it; a 10×20 works if the garage and basement stay out.
10×20
A car needs a 10×20 (200 sq ft): long enough for a sedan, SUV or pickup with room to open the door and a few boxes along the wall. Ask the facility for a drive-up unit with a roll-up door.
5×5
A 5×5 is 25 square feet, the floor of a small closet, and holds about 200 cubic feet: boxes, a chair, a small dresser or a twin mattress. Some facilities also rent lockers smaller than that.
Unit sizes
Self-storage units come in a handful of standard floor sizes with 8-foot ceilings. The cubic feet are what each holds when it's loaded the way a crew loads a truck.

A rented unit is only part of the cost: there's the truck, the loading and, later, the unloading. Red Cat's moving and storage does all of it for one monthly price, our moving prices page has every rate, and the moving truck size calculator and the moving boxes calculator use the same list for the rest of the move; the moving cost calculator prices the move itself, and the storage cost calculator prices the storage by the month.
