King Size Mattress Dimensions: The Complete Size Guide in Feet, Inches, CM and MM

A king size mattress ordered without checking the actual dimensions against the bed frame is a problem that shows up at delivery, not at checkout. This guide covers king size mattress dimensions in every unit, super king sizing, how the UAE standard compares to other markets, and what room size actually works before committing to this size.

What Are the Dimensions of a King Size Mattress?

What are the dimensions of a king size mattress in the UAE: 200cm long by 180cm wide. Here's that across every unit:

The 20cm figure on our product pages refers to mattress thickness, not the sleeping surface. That stays at 200 x 180cm across our full king range.

King Size Mattress Dimensions: Which Unit to Use and When

CM is the most useful unit when checking against a UAE bed frame, since most local frames list internal dimensions in centimetres. Always measure the inside of the frame, not the outer edge, since manufacturers vary by a few centimetres even within the same size category.

Inches matter most when comparing against international standards. The UAE king size mattress dimensions in inches at 78.7 x 70.9 inches doesn't match the US King at 76 x 80 inches. The UAE version is wider but shorter, so an imported American frame and a UAE king mattress won't align.

King size mattress dimensions in mm: 2000 x 1800mm. This comes up in technical contexts: fitted wardrobes, built-in frames, or custom joinery where a few millimetres determines whether the mattress sits flush.

For room planning, king size mattress dimensions in feet rounds to 6.5 x 6 feet for the mattress surface alone.

King vs Super King: How the Dimensions Compare

Super king size mattress dimensions add 20cm of width. That's roughly 8 inches across the shared sleeping surface, which sounds modest but makes a real difference when two people are sleeping on different schedules or actively using the full width of the bed.

Length stays at 200cm across both sizes in our UAE range.

Indian King Size Mattress Dimensions

Indian king size mattress dimensions follow a square format: 72 x 72 inches, approximately 183 x 183cm. The UAE king at 200 x 180cm is longer and slightly narrower.

Anyone moving between India and the UAE and bringing a bed frame with them should check which standard the frame is built to before ordering a mattress. An Indian king frame leaves a gap at the foot of a UAE king mattress, since the UAE length runs 17cm longer.

King Size Bed Mattress Dimensions and Room Planning

King size bed mattress dimensions change how much usable floor space a room has left after the bed is placed. Before committing to this size, check the room against these practical thresholds:

The 60 to 90cm clearance rule on each side of the bed is worth taking seriously. Less than that and wardrobe doors, curtain access, and general movement around the bed start feeling squeezed.
