Bedding Size Converter

The International Bedding Size Converter is a free browser tool that converts bed and mattress sizes between regions. Choose your region (United States, United Kingdom, Europe, or Australia), pick a size name (e.g. Queen, King, Single), and see exact dimensions in centimetres and inches plus the closest equivalent size names in other regions. No sign-up required; everything runs in your browser.

Why Use This Converter?

• Shop abroad with confidence — Order sheets or mattresses from another country and know exactly which size to choose.
• Avoid returns — Matching US Queen to UK or EU sizes prevents wrong fits and extra shipping costs.
• Quick reference — Get cm and inch dimensions and regional names in one place instead of searching multiple charts.
• Accurate equivalents — The tool uses standard mattress dimensions and finds the closest match in each region.

Key Features

• Four regions: US, UK, Europe (EU), Australia.
• Standard sizes only: Twin, Full, Queen, King, Single, Double, Super King, and regional variants (e.g. Twin XL, California King, King Single).
• Dual units: All results in cm and inches.
• Equivalent sizes: See the closest size in the other three regions for easy comparison.
• Copy result: One-click copy of the selected size and dimensions for pasting into notes or emails.

How It Works

Bed sizes are defined by width and length. Each region uses different names and slightly different dimensions. This tool uses common standards: US sizes (e.g. Twin 96.5×190.5 cm), UK and EU sizes (e.g. Single 90 cm width, 190–200 cm length), and Australian sizes (e.g. King Single, Queen). When you select a size, it shows the dimensions and finds the closest match in the other regions by comparing width and length so you can choose the right bedding or mattress when buying across borders.
