When it comes to choosing the right mattress, a single mattress size is one of the most popular options for people who want a comfortable yet space-saving bed. Whether you are buying it for your child, a guest room, or even for yourself, the single mattress size offers great versatility. Many people find it confusing to pick the right mattress because they are unsure about exact measurements, space requirements, and comfort levels. In this blog, we will explore everything you need to know about single mattress size, along with the exact single mattress dimensions, benefits, and tips for buying the best one for your needs.
What is a Single Mattress Size?
A single mattress size is typically designed for one person. It is smaller than a double or queen mattress but still provides enough sleeping space for a comfortable night’s rest.Thus the single mattress dimensions (90 cm × 190 cm) are the reference point for beds, frames, sheets, and accessories. When you aim to purchase a single mattress size, you want to ensure that your frame, bedding, and room layout are all suited for those single mattress dimensions.
The single mattress size is also ideal for hostels, dorm rooms, small bedrooms, and rental apartments where space is limited. Since it is lightweight and compact, moving and setting up a single mattress size is much easier compared to larger mattresses.
Why the Single Mattress Size (90 × 190 cm) Matters
Understanding that the single mattress dimensions are 90 × 190 cm helps in many ways:
- Fit in your frame: If your bed frame is built for 90 by 190 cm, a true single mattress size will match snugly.
- Room planning: You can allocate floor space in your room based on those single mattress dimensions.
- Bedding and accessories: Sheets, covers, mattress protectors, and toppers must match the single mattress size (90 × 190 cm).
- Comparisons to other regions: In some other countries, a “twin” mattress might be a different size but for UK standard dimensions, single mattress size means 90 × 190 cm.
Single Mattress Size for Different Users
For Children and Teenagers
A single mattress size (90 × 190 cm) is often ideal for a children’s bed. It gives enough length for growing kids while not occupying too much room. Because the single mattress dimensions are modest, you can still include desks, wardrobes, or shelves in the same room without overcrowding.According to sleep foundation, for growing children, choose a mattress that provides firm support to properly support their bones and joints
For Adults Sleeping Alone
Many adults choose a single mattress size when space is tight, such as in studio flats or small homes. The 90 × 190 cm single mattress dimensions allow a full-length sleep for single sleepers, provided they are not exceptionally tall (over ~190 cm). If you are significantly taller, some brands offer “extra-long single” variants, but the standard “single” line uses single mattress dimensions of 90 by 190 cm.
Guest Rooms & Spare Beds
Because the single mattress size is compact and cost-effective, it’s frequently used in guest rooms. A spare bed with single mattress dimensions is easy to manage, move, and tend to without consuming too much floor area.
Single Mattress Size vs. Larger Sizes: When to Use It
Let’s compare the single mattress size (90 × 190 cm) with a few larger sizes to see when it is and isn’t appropriate:
| Size Name | Width (cm) | Length (cm) | Notes |
|---|---|---|---|
| Single Mattress | 90 | 190 | This is the single mattress size |
| Double Mattress | 135 | 190 | Common for couples in smaller rooms |
| Queen Size Mattress | 120 | 190 | A midpoint between double and king |
| King Size Mattress | 150 | 200 | More spacious for couples |
| Super King Mattress | 180 | 200 | Largest standard UK size |
- Single Mattress Size (90 × 190 cm): Ideal for one person, small rooms, child beds, guest beds.
- Double Mattress (135 × 190 cm): Gives more width for a person who moves around, or for couples in narrow bedrooms.
- Queen Size (120 × 190 cm): Offers more width than a single but remains comfortable in many rooms.
- King / Super King (150 × 200 cm / 180 × 200 cm): Best suited when space is abundant.
If your room is too narrow or you’re primarily a single sleeper, the single mattress size is a smart choice. But if you anticipate needing more space or potentially sleeping with a partner, one of the larger sizes may be better.According to sleep foundation, to avoid a cramped feeling, we recommend leaving about 24 inches of space around each side of your bed.
