Country Size Comparison
Pick any two countries and see their outlines side by side at identical map scale, with true spherical areas in km² and a plain-English size ratio.
How to use this tool
- 1Type or pick Country A and Country B.
- 2Read the headline ratio and each country's true area.
- 3Use Swap to flip the comparison.
Quick answer: Compare two countries at true scale — no Mercator distortion. Coverage: Worldwide. No account is required.
What Country Size Comparison is designed to answer
Country Size Comparison is built for people who need a practical answer about country size comparison without opening a full GIS package. Pick any two countries and see their outlines side by side at identical map scale, with true spherical areas in km² and a plain-English size ratio. The result is most useful as a transparent planning or reference output: you can see the inputs, inspect the map where relevant, and compare the answer with related MapBench tools before treating it as a decision.
This page focuses specifically on country size comparison and true size of countries. That distinction matters because nearby tools may use a different geographic model — for example straight-line geometry, road-network travel time, an administrative boundary or a public dataset. Use the method and limitations sections below to understand what the number or map represents before reusing it in a report.
When this tool is useful
Use Country Size Comparison when the question matches the method the page actually uses. Typical workflows include:
- Answer a one-off question about country size comparison and keep the result tied to a visible map or explicit input.
- Compare two or more scenarios involving true size of countries without creating an account or installing desktop software.
- Use the output as a planning or teaching reference, then move to an official or specialist source if the result affects legal, safety, engineering or financial decisions.
Worked examples
These examples are meant to show how to interpret this kind of output, not to replace the values produced from your own inputs.
- Small pin map — A handful of labelled pins is usually clearer than dozens of unstyled markers. Use categories or colours only when they carry meaning.
- Shareable state — When a tool stores settings in the URL, recipients can reopen the same configuration without an account.
- Export choice — PNG is useful for presentation; GeoJSON or CSV is better when the data needs to remain editable.
How to interpret the result
The most common errors come from using a correct result to answer the wrong geographic question. Keep these points in mind for Country Size Comparison:
- Choose colour for category, not decoration: two or three high-contrast hues read instantly; a rainbow reads as noise. Labels carry identity, colour carries grouping, and the viewport should crop tightly to the subject.
- Export twice: an image for the slide and a data format (GeoJSON/CSV) for the record. The image communicates; the data survives editing, and the pair keeps your map honest and reusable.
Limits & appropriate use
Custom maps inherit two honest limits: the basemap's and the message's. The basemap is OpenStreetMap's current picture with its ODbL attribution ask, and its gaps — new roads, thin rural detail — travel into every export that includes tiles. The message limit is design's classic one: a map can carry one argument well, and beyond a few dozen symbols the right instrument changes to data-driven mapping with clustering and categories. Both limits are stated where they matter, because the alternative is a beautiful figure that misleads its own author.
Within those bounds the workflow is complete and durable: pins, labels, colours, tight framing, pixel-ratio PNG for the slide, GeoJSON/CSV for the record, URL-state for the living version. Escalation is gentle by design — choropleths and territory shading belong to GIS with real boundaries (the blank-map library and GeoJSON exports feed it), cartographic print production wants vector pipelines, and brand-strict design systems want tokens this tool deliberately doesn't fake.
- Data-dense maps → CSV-to-map with clustering and category colour.
- Boundary shading/choropleth → GIS with census or OSM boundaries.
- Print cartography → vector exports into a design pipeline.
Data & methodology
Map imagery derives from OpenStreetMap via OpenFreeMap (ODbL attribution applies to reused basemap images); your pins and labels live only in the share URL.

Key terms worth knowing
- Share-state URL
- Encoding the whole map configuration in the link itself.
- Pixel-ratio export
- PNG export at device resolution for crisp slides and print.

Editorial guidance: MapBench explains the method and limitations so the tool can be used as a transparent reference, not as a black-box answer. For legal boundaries, safety-critical routing, surveying, engineering, regulated decisions or official statistics, verify the result with the responsible authority or a qualified professional.

Frequently asked questions
Clear answers about the calculation, accuracy and appropriate use.
Why do countries look bigger on most maps?
The Mercator projection stretches areas near the poles — Greenland looks as big as Africa on it, but Africa is about 14× larger in reality. This tool draws both countries at the same scale.
Are the km² figures accurate?
Areas are computed as true spherical areas from the country polygons — no projection stretching. Outlines use a simplified world dataset, so figures are approximate at the percent level.
How is the comparison drawn?
Both outlines are rendered with the exact same degrees-to-pixels scale and centered in their boxes, so on-screen sizes are directly comparable.
Can I compare more than two countries?
Compare two at a time. Run a second comparison to chain results — e.g. compare A vs B, then B vs C.
Why does Russia look cut off?
Russia crosses the antimeridian (180°). The simplified outline spans the full width; its area figure is still correct.
