The 10 × 30 storage size.
A 300-square-foot footprint with three times the depth of a 10 × 10. Treat it as several organized zones connected to the entrance.
300 square feet of floor space
10 feet wide × 30 feet deep = 300 square feet. Height is a separate measurement. The model starts with an editable height; the actual unit, door and usable clearances need a facility check.
What could you put in it?
Plan the back of the room first and work toward the door. Give each group a clear name, keep a location note with each box, and separate items you retrieve often from long-term storage.
A bedroom or apartment label is only a starting list. Two households can have very different furniture and box counts. Use your actual collection to decide.
Start with boxes in this size →Check the shape, not just the volume.
A long room makes retrieval distance important. Check the actual interior, columns, door and any facility restrictions before choosing a layout or assuming a permitted use.
Measure width, depth and height with the furniture in the position you can safely store it. Allow for padding, handles and parts that cannot be removed. Confirm whether an item may be tipped or stacked before using that arrangement.
Make the space useful after move-in.
Keep a continuous route down the length and make shelf fronts accessible. Test whether a bulky item can leave its zone without dismantling the surrounding stacks.
Use access paths and shelves in the planner, then name boxes and record their contents. Compare both a packed layout and the layout you would want to visit.

Compare a 10 × 20 if your own list can stay accessible in less space. The goal is a useful layout, not automatically the biggest model.
Questions about a 10 × 30 space
How big is a 10 × 30 storage unit?
The nominal footprint is 10 feet wide by 30 feet deep, or 300 square feet of floor area. Usable interior dimensions, ceiling height and the door opening can differ from the size label. Confirm those measurements with the facility.
Will my belongings fit in a 10 × 30?
Make a list, measure the largest pieces and test their arrangement with boxes, shelves and an access path. Total volume alone cannot establish fit. The planner gives an estimate to check against the real unit and doorway.
How much does a 10 × 30 cost, and is one available?
This guide compares a generic footprint and does not list an available unit or a price. Use Find a space to tell the team your needs and move-in date. They confirm the actual unit, current price, access and next steps.
