How to choose the right size loft bed for me?

If you are wondering if the OP Loftbed will fit in your particular room, here are the overall (outside to outside) dimensions for each size:
Twin: 46" Wide X 83" Long X 90 3/4" Tall
Twin Extra Long: 46" Wide X 88" Long X 90 3/4" Tall
Full: 62" Wide X 83" Long X 90 3/4" Tall
Queen: 70" Wide X 88" Long X 90 3/4" Tall
King: 88" Wide X 88" Long X 90 3/4" Tall

On the Tall Height (Original) OP Loftbed the mattress platform is adjustable to:
60-1/2", 63-1/4", or 66" above the floor. On the Medium Height OP Loftbed, the mattress platform is adjustable to 49 1/2", 46 3/4", or 44" above the floor. On the Short Height OP Loftbed, the mattress platform is adjustable to 33", 30 1/4", or 27 1/2" above the floor. Check out our free general dimensional drawing for more details.

We are always hesitant to recommend a particular size loft because mattress thickness can vary, ceiling heights vary, and some people prefer more room above or below than others do. However, we do offer a free general dimension drawing that will help you figure this out for yourself. Also, up to 12-inches can safely be added to the bottom of the legs to accommodate nearly height you might need. Most customers with standard 8-foot ceilings are fine with a tall height loft bed.

The uprights on the Tall Height OP Loftbed can also be shortened somewhat to fit rooms with low ceilings.
