A normal double mattress, also known as a standard double, measures 135cm wide and 190cm long in metric units. This size is equivalent to 4 feet 6 inches wide and 6 feet 3 inches long when measured in imperial units.
Standard Double Mattress Dimensions
According to standard specifications, a double bed and mattress are designed to comfortably sleep two adults. The dimensions are consistent across these standard sizes, offering a practical sleeping space for couples or individuals who prefer extra room.
Here is a clear breakdown of the standard double mattress dimensions:
| Measurement Unit | Width | Length |
|---|---|---|
| Metric | 135 cm | 190 cm |
| Imperial | 4 feet 6 inches | 6 feet 3 inches |
This standard size, often referred to simply as "4'6"", provides a balanced footprint for many bedrooms while still offering sufficient space for two people to rest. Understanding these specific measurements is crucial when purchasing bedding, bed frames, or planning bedroom layouts.
For example, when buying a fitted sheet, you would typically look for one specified for a "standard double" or one matching these exact dimensions (135cm x 190cm or 4'6" x 6'3").
Choosing a mattress of this size is a common decision for couples moving into their first home or individuals upgrading from a smaller single bed. It represents a widely available and practical option in the mattress market.
