Visual bed-size comparison
Overlay proportional bed sizes across the US, UK, Europe, Brazil, and Australia.
Choose up to eight sizes. Every overlay uses one proportional scale.
These are mattress-top proportions, not bed-frame outer dimensions.
Planning boundary
Useful geometry, not a purchase guarantee.
Results use the values you enter and the source-backed nominal mattress records in this site. Finished products, frames, elastic construction, room obstructions, and manufacturer tolerances can change real-world fit.
Bedroom layouts are planning guidance, not building-code, accessibility, fire-safety, or professional design determinations.
