WhatSizeOf is an interactive size comparison tool that helps you understand the real dimensions of objects by comparing them side by side. Simply select two objects from our library, and our tool will show you an accurate visualization of their relative sizes, complete with measurements and scale ratios.
Our size comparisons are highly accurate, based on official specifications and standard measurements from manufacturers and authoritative sources. Each object in our database has been carefully researched to ensure the dimensions reflect real-world sizes. We use precise visualization techniques to maintain accurate proportions.
You can compare over 100+ different objects including everyday items (phones, credit cards, cans), furniture (beds, tables, chairs), vehicles (cars, bikes), electronics (laptops, TVs), and even landmarks and buildings. Our library is constantly growing based on user requests.
WhatSizeOf supports both metric (centimeters, meters) and imperial (inches, feet) units. You can easily switch between unit systems using the unit switcher in the top navigation. The tool automatically selects the most appropriate unit based on object size.
