Why Bed Size Matters More Than You Think
Choosing the right bed size isn't just about comfort — it affects how your whole bedroom feels. Too large and the room feels cramped; too small and you'll wake up wishing you'd gone bigger. This guide walks you through every standard UK bed size so you can make a confident, informed decision. It will help you to create the perfect space for reading in bed and a refreshing night's sleep.
UK Standard Bed Sizes at a Glance
UK bed sizes differ from European and US standards, so it's important to use the right measurements when shopping. Here's a quick reference:
- Small Single (2'6" / 75cm wide/ 190cm deep) — Ideal for young children or very compact rooms.
- Single (3' / 90cm wide/ 190cm deep) — The most popular choice for children's bedrooms and guest rooms. Our Astley Single Bed in Grey and Astley Single Bed in Antique Oak are crafted from solid hardwood for lasting quality.
- Small Double / 4 Foot (4' / 120cm wide/ 190cm deep) — A smart choice for teenagers or adults in smaller rooms who want more space than a single. See our Astley 4 Foot Bed in Grey and Astley 4 Foot Bed in Antique Oak.
- Double (4'6" / 135cm wide/ 200cm deep) — The UK's most popular adult bed size. Comfortable for couples in smaller rooms or generous for a single sleeper. Browse our Astley Double Bed in Grey and Astley Double Bed in Antique Oak, as well as the stylish Inglewood Double Bed in White.
- King Size (5' / 150cm wide/ 200cm deep) — The go-to choice for couples who want extra space. Our Astley King Size Bed in Grey and Astley King Size Bed in Antique Oak bring solid hardwood craftsmanship to this popular size. Also available in the contemporary Inglewood King Size in Black and Inglewood King Size in White.
- Super King (6' / 180cm wide/ 200cm deep) — Maximum sleeping space for those who want the ultimate in comfort. Our Camille Super King with Oatmeal Linen Headboard and Genesis Super King with Dark Grey Linen beds are available in this size.
How to Measure Your Room
Before you buy, measure your bedroom carefully. As a rule of thumb, leave at least 60–70cm of clearance on each side of the bed for comfortable movement, and ensure there's enough space to open wardrobes and drawers fully. Sketch out your room to scale — it makes a huge difference.
Who Is Each Size Best For?
Single beds are perfect for children's rooms, guest rooms, or compact spaces. Small doubles suit teenagers or adults in box rooms. Double beds are the sweet spot for most couples in standard UK bedrooms. King size is ideal if you have the room and want to sleep undisturbed. Super king is a luxury choice for large master bedrooms.
Don't Forget the Mattress
Always buy a mattress that matches your bed frame size exactly — UK sizes are standardised, but always double-check the dimensions before ordering.
Mattresses are sold separately.
Due to Bunk Bed Safety Regulations, only the Premier or Platinum Mattress is suitable for use on the upper bunk. Requires a Standard UK Single Mattress (90cm x 190cm x 18cm).
