We built TrueSize.net because we kept seeing maps that misrepresent the real size of countries and regions due to Mercator distortion. Most “true size” maps stop at countries and give rough approximations — we wanted something that goes far beyond that. With TrueSize.net, you can explore 3,700+ subnational regions like U.S. states, German Länder, and Japanese prefectures, as well as 9,000+ historical territories from the USSR to the Roman Empire. You can drag them, overlay them, and even rotate them — and everything stays in true scale using accurate spherical math. One of the features we’re most proud of is the custom data tools. TrueSize.net isn’t just a map for looking at countries — it’s a full geo tool. You can: - Import your own GeoJSON or TopoJSON data to bring in any custom map or dataset - Move, drag, and overlay features while keeping their true size and proportions intact - Export your modified maps for use in presentations, reports, or further analysis This makes TrueSize.net a unique tool: it lets you not only explore but actually manipulate maps in true scale, whether you’re comparing regions, visualizing historical boundaries, or creating custom projections. It’s perfect for educators, historians, data journalists, and map enthusiasts who want to interact with geographic data in ways that traditional maps simply don’t allow. We’re especially proud that TrueSize.net is interactive, flexible, and educational — a tool that makes the true scale of the world tangible for anyone curious about geography, history, or data visualization.
