Quick answer

Loft beds are tall: the three below are 50 inches (a low loft), 68.5 inches and 72 inches. On a 96 inch ceiling that leaves 46, 27.5 and 24 inches above the top of the frame, and the mattress and sleeper sit inside that gap. The CPSC bunk bed guidance, which does not mention loft beds, defines a bunk bed as one whose mattress foundation is more than 30 inches above the floor and requires guardrails at least 5 inches above the mattress. Check the label on the bed you receive for the allowed mattress thickness.

What the CPSC pages say

We opened the CPSC business-guidance page for bunk beds on 2026-10-01. It defines a bunk bed as a bed with the bottom of its mattress foundation more than 30 inches above the floor, and says lower bunks with foundations 30 inches or less from the floor do not have to have guardrails. It says guardrail tops must be at least 5 inches above the top of the mattress and that beds must be marked or labeled with the proper mattress size and thickness and with warnings for safe use. The page does not name loft beds or single-surface structures. We therefore treat it as the closest published rule for a raised bed and check each loft against it by number, not by name. The CPSC release on the standard says the label warns not to place children under 6 years on the upper bunk. Whether a particular loft carries that label is something to check on the bed.

Worked example: a 96 inch ceiling

Say the ceiling is 96 inches (an assumption, so measure yours). The three loft beds leave:

• Low loft, 50 inches tall: 96 minus 50 leaves 46 inches above the frame.
• High loft, 68.5 inches tall: 96 minus 68.5 leaves 27.5 inches.
• Metal loft, 72 inches tall: 96 minus 72 leaves 24 inches.

That gap holds the mattress thickness plus the sleeper. With a 24 inch gap and a 6 inch mattress (an assumption) there are 18 inches above the mattress, so check whether the sleeper can sit up in bed. The Max & Lily listing for the high loft says it suits standard 8-foot ceilings. For a sleeper who wants to sit up in bed, the low loft at 50 inches is the choice, with the trade-off of less space underneath.

Worked example: floor space

The high loft’s listing gives a total footprint of 96.5 by 59.5 inches including the ladder at the end and the desk, which is 5,742 square inches or 39.9 square feet (96.5 times 59.5 divided by 144). A twin mattress is 38 by 75 inches, 2,850 square inches or 19.8 square feet (Amerisleep). So the loft with its desk takes about twice the floor of the mattress, but the floor under the bed is open. The metal loft at 80 by 42 inches takes 3,360 square inches, 23.3 square feet, and the low loft at 81.5 by 54.25 inches takes 4,421 square inches, 30.7 square feet.

In a 10 by 10 foot room (120 inches), the high loft’s 96.5 inch length leaves 120 minus 96.5, which is 23.5 inches, so a door on that wall must clear it.

Under-bed space

The high loft listing states an under-bed height of 51.5 inches, which is the clearance for a desk and a chair. The metal loft’s table gives a ground-to-item distance of 68 inches, so the usable clearance is a little less than that, which the listing does not state. The low loft’s total height of 50 inches leaves less than 50 inches under the bed. The high loft’s listing says its desk must be attached to the loft and is not designed as a standalone desk.

We have not tested these. The numbers are from the Amazon measurement tables and bullets. The two Max & Lily pages showed no cart button and the East West page showed “cannot be shipped to your selected delivery location” from Vietnam; that is a shipping limit or a missing offer from where we opened them, not a stock notice.

Max & Lily twin high loft bed with ladder on the end and desk, clay. There is no measurements table. The bullets give New Zealand pine, a 400 pound weight capacity, strong plywood slats with a metal support bar, an assembled size of 96.5 by 59.5 by 68.5 inches including the ladder and desk, an under-bed height of 51.5 inches and a note that it suits standard 8-foot ceilings. Best for: a room with an 8-foot ceiling that needs a desk space. Watch out: the 27.5 inches above the frame.

Max & Lily classic low loft, twin, with pull-out desk, white. The table gives 81.5 inches long, 54.25 wide and 50 high. The bullets give knot-free solid pine, a 400 pound weight capacity, plywood slats with a metal support bar, an angled ladder with anti-slip steps and the seller’s statement that the low profile suits low ceilings and younger children. Best for: a low ceiling or a younger child. Watch out: less space underneath than the high loft.

East West Furniture Buckland twin metal loft bed with desk and shelves, white. The table gives 80 inches long, 42 wide, 72 high and 97 pounds, a ground-to-item distance of 68 inches and a maximum weight recommendation of 250 pounds. The bullets give a metal and wood build, a table top, two shelves and two ladders with 3 and 4 steps, plus guard rails. Best for: a small footprint of 42 inches wide with a desk built in. Watch out: the 250 pound limit is the lowest, and at 72 inches it leaves only 24 inches under a 96 inch ceiling.

Mistakes to avoid

Ordering without the ceiling height. A 72 inch loft leaves 24 inches under a 96 inch ceiling.

Counting the ladder out. The high loft is 96.5 inches long with the ladder and 81.5 without.

Skipping the mattress thickness. Read the label for the allowed thickness; the guardrail must be 5 inches above the mattress.

Using the desk alone. The high loft’s listing says its desk must be attached to the loft.

Putting a young child on a high loft. The CPSC label for bunk beds warns not to put children under 6 on the upper bunk.

When you may not need a loft bed

If the ceiling is under about 8 feet, a low loft or a standard bed with a desk beside it avoids the headroom problem. If you need two beds, see the bunk beds guide and the triple bunk bed guide. For a regular twin bed, see the twin bed frame guide.
