A single bed in India is 3 feet wide and 6.25 feet long: 36 × 75 inches, or 91 × 190 cm. Many makers also sell a 3 × 6 feet single (36 × 72 inches), and a few sell 36 × 78. The width is the fixed part; the length varies by a few inches, so check the listing before buying a mattress.

Who a single bed suits
One adult. 36 inches is enough for one person to turn over. Anyone over 6 feet tall should buy the 78-inch length.
A child from about six. A single lasts into the teens; a toddler bed does not.
A guest room or a study that doubles as a bedroom, where a sofa cum bed is the alternative.
Hostels, PGs and rented rooms, where a single with a storage box under it replaces a cupboard.
It does not suit two adults, even for a night. For that the next size up is a double (48 inches), and for regular use a queen.
Single beds with storage
A single bed is the size where storage pays off most, because the rooms it goes in are small. A box storage single has a lid that lifts; a drawer single has one or two drawers on the long side, which needs 24 inches of clear floor there to open. Hydraulic lift singles exist but are rarer. The catalogue marks the storage type on each bed, and the storage filter on the Single Bed page narrows to one type.
What is the single bed mattress size in India? 36 × 72 or 36 × 75 inches, usually 4 to 6 inches thick. Match it to the frame length in the listing.
Is a single bed 3×6 or 3×6.25? Both are sold. 3 × 6.25 (36 × 75) is the more common of the two for adult beds.
Can two single beds make a king? Two 36 × 78 singles side by side are 72 × 78, exactly a king. It is a common hotel arrangement and works at home with a mattress bridge.
