Bed Size and Layout Planner: Find the Right Bed for Your People and Your Room

Quick answer

Your bed should be at least about 15 cm longer than the tallest sleeper, give each adult enough shoulder width, and leave walkways of roughly 60 to 90 cm around it. The planner applies those rules to your people, your country's size chart and your room, then draws the result to scale.

Bed Size & Layout Planner

Find the right bed size from heights, weights, sleepers, usage and room size, drawn to scale.

The three rules it uses

Length: tallest person plus about 15 cm so feet do not hang off. Width: each adult needs space for shoulders and turning, which grows with body size; children and pets need less. Clearance: walkways around the bed so you can move, make the bed and open wardrobes.

How often you use the room matters

A master bedroom used nightly deserves more space than a guest room used a few times a year. The planner changes its comfort target and suggests a sofa bed or a smaller size for occasional rooms.

When a standard size does not fit

If no standard size fits your room or frame well, the planner suggests an exact custom size in millimetres and sends it to the Studio.

Frequently asked questions

Which size is best for two adults?

Queen (about 150-160 cm wide) is a practical minimum; King or larger gives more room, if the room allows.

What if my room is small?

The planner shows the largest size that still leaves a walkway, and suggests a custom size or a platform bed with storage.

Does it work for children and pets?

Yes. Add them as sleepers and the width requirement updates.
