Buyer ToolsBunk Bed Size Guide India — Standard Sizes in Feet and mm
Ordering bunk beds for a hostel, school or staff housing block starts with one question: what size? Get it wrong and mattresses don't fit, students hit their heads on the upper bunk, or fewer beds fit each room than you planned. This guide gives the standard bunk bed sizes used in India in feet, inches and millimetres, the heights that matter, and how to work out how many bunk beds fit a room.
Standard Bunk Bed Size in India — Quick Answer
Most hostel bunk beds in India are built around a standard single mattress of 3 × 6 feet (36 × 72 inches, about 915 × 1830 mm). The steel frame adds a little on each side, so the bed's footprint is usually 50–100 mm wider and longer than the mattress. A typical double-decker hostel bunk bed stands about 5.5 to 6 feet (1650–1830 mm) tall.
| Mattress size (inches) | Mattress size (mm, approx.) | Typical use |
|---|---|---|
| 30 × 72 | 760 × 1830 | Compact rooms, junior school hostels |
| 36 × 72 (3 × 6 ft) | 915 × 1830 | Most college and university hostels |
| 36 × 75 | 915 × 1905 | Senior students, staff housing |
| 36 × 78 (3 × 6.5 ft) | 915 × 1980 | Taller adults, worker and staff accommodation |
Single mattresses in India are 36 inches wide and come in lengths from 72 to 78 inches, so fix the mattress first and have the bed frame made around it.
Bunk Bed Heights That Matter
The overall height is less important than the three heights inside it:
| Measurement | Typical range | Why it matters |
|---|---|---|
| Floor to lower bunk deck | 300–400 mm (12–16 in) | Comfortable to sit on; higher if drawers go underneath |
| Lower mattress top to underside of upper bunk | 800–900 mm (31–35 in) | Lets an adult sit up on the lower bunk without hitting their head |
| Overall bed height | 1650–1830 mm (5.5–6 ft) | Must leave enough space to the ceiling for the upper sleeper |
| Upper mattress top to ceiling | at least 750–900 mm (30–35 in) | Room to sit up and climb in safely |
Most Indian hostel rooms have ceilings of around 9 to 10 feet, which is comfortable for a standard two-tier bunk bed. Check rooms with a low false ceiling, beams or ceiling fans directly above the upper bunk before you finalise the height.
Guard Rail Height and Mattress Thickness
The upper bunk needs a guard rail on both long sides (or on the open side and the wall side), so a sleeping student cannot roll off. A widely used benchmark is the US Consumer Product Safety Commission rule for bunk beds, which requires the top of the guard rail to stand at least 5 inches (about 125 mm) above the top of the mattress.
- Use a thinner mattress on the upper bunk — about 4 inches (100 mm) is common — so the guard rail stays high enough.
- If you use thicker mattresses, the guard rail has to be taller. Agree the mattress thickness before the beds are made.
- The ladder should be fixed firmly to the frame, with flat steps rather than round rods if students climb barefoot.
How Many Bunk Beds Fit in a Room?
A bunk bed for a 3 × 6 ft mattress takes up roughly 1.0 × 1.9 m of floor. Add a clear walkway of about 750–900 mm in front of the beds, plus space for lockers or wardrobes and a study table if the room needs one.
| Room size (approx.) | Bunk beds | Students | Space left for |
|---|---|---|---|
| 3 × 3.5 m | 1 | 2 | 2 lockers or wardrobes, 1–2 study tables |
| 3.5 × 4 m | 2 | 4 | 4 lockers or wardrobes |
| 4 × 5 m | 3 | 6 | 6 lockers, a small walkway |
| 5 × 6 m | 4 | 8 | 8 lockers, shared table |
These are planning estimates, not rules — doors, windows, columns and local hostel norms change the answer. Our accommodation planner works out how many beds fit your room, and we send a layout drawing with every quotation.
Bunk Beds With Under-Bunk Drawers
In small rooms, steel drawers under the lower bunk replace a separate wardrobe for each student. The lower bunk sits higher to make room for the drawers, so allow for that in the sitting height and in the gap to the upper bunk. If students already have wardrobes or lockers, a plain bunk bed without drawers keeps the price down.
Steel vs Wooden Bunk Beds
For hostels and staff housing, steel bunk beds are the usual choice: they carry two sleepers without loosening at the joints, resist termites and damp, and can be cleaned easily between batches of students. Wooden bunk beds suit homes and premium accommodation where looks matter more than heavy daily use. See our steel vs wooden furniture guide for a fuller comparison.

Frequently Asked Questions
What is the standard size of a bunk bed in India?
Most hostel bunk beds in India are made for a 3 × 6 ft single mattress (36 × 72 inches, about 915 × 1830 mm). The frame is usually 50–100 mm wider and longer than the mattress, and the bed stands about 5.5 to 6 feet tall.
What is the height between the two bunks?
Leave about 800–900 mm (31–35 inches) between the top of the lower mattress and the underside of the upper bunk, so an adult can sit up on the lower bunk without hitting their head.
What ceiling height do I need for a bunk bed?
Allow at least 750–900 mm (30–35 inches) between the top of the upper mattress and the ceiling. Most Indian hostel rooms, with ceilings of about 9 to 10 feet, are fine for a standard two-tier bunk bed.
How high should the guard rail be on the top bunk?
A widely used benchmark is the US CPSC bunk bed rule: the top of the guard rail should be at least 5 inches (about 125 mm) above the top of the mattress. Use a thinner mattress, about 4 inches, on the upper bunk.
What mattress size fits a hostel bunk bed?
A standard Indian single mattress, 36 inches wide and 72 to 78 inches long. Fix the mattress size first and have the bunk bed made around it.
Can you make bunk beds to a custom size?
Yes. The Royal Safe Company makes steel bunk beds to your mattress size and room layout, with or without under-bunk drawers, and confirms the size with a drawing. There is no minimum for standard models in India; custom designs need 25 pieces.
