Bunk Bed Size in Feet, cm and Inches: Hostel Bed Size Guide (2026)
Quick answer
Most hostel bunk beds in India take a standard single mattress of 6 × 2.5 ft (72 × 30 in, about 183 × 76 cm) or 6 × 3 ft (72 × 36 in, about 183 × 91 cm). Always check the ceiling height and leave enough headroom above the top mattress for the sleeper to sit up.
Size decides three things: which mattress you buy, how many beds fit in a room, and whether the top deck is comfortable. Here are the numbers.
What is the standard bunk bed size?
A bunk bed is sized around its mattress. In India, hostel bunk beds are almost always built for single mattresses:
| Size | Feet | Inches | cm | mm |
|---|---|---|---|---|
| Standard single | 6 × 2.5 | 72 × 30 | 183 × 76 | 1829 × 762 |
| Wide single | 6 × 3 | 72 × 36 | 183 × 91 | 1829 × 914 |
Frame dimensions are slightly larger than the mattress. Confirm the exact outside size with your supplier before planning the room.
How much ceiling height do you need for a bunk bed?
Measure from the top mattress surface to the ceiling. The person on the top deck should be able to sit up without hitting the ceiling or a fan — check fan blades especially. Low ceilings and ceiling fans are the most common reasons to choose single cots instead.
How much gap should there be between the two decks?
Enough for the lower sleeper to sit up comfortably. When you compare models, sit on the lower deck yourself or ask the supplier for the clear height between decks.
How many bunk beds fit in a hostel room?
- Each bunk bed uses the floor area of one single cot but sleeps two.
- Leave a clear walkway along the long side of each bed.
- Keep windows, switches and doors reachable.
- Place ladders on the walkway side, never against a wall.
