Measurement basis & sources
Source — All source Mexico polygons, including represented islands. Lambert equal-area projected east-west boundary span; not surface distance. Generalised source borders and small islands are approximate.
Actual measurement source available after you lock in.

Size It Up: Geography

Size It Up Geography on Sizes.games: Recognise a country or island group, then compare its outline with another map at the reference scale. Geography asks you to estimate a projected north–south or east–west span, rather than land area. Read the direction and included territory before resizing. Play the category’s five-round Daily game, or practise with new five-round games in Unlimited.

Compare map spans, one direction at a time

These are teaching ratios, not measurements of objects in today’s game.

Twice the north–south span

A map twice as tall along the stated projected axis has twice that span. This says nothing by itself about the land area inside the outline.

Half the east–west span

Compare the labelled horizontal span, keeping the stated territory scope in mind. An island beyond the mainland can change the endpoints of that span.

Maps in the current library

Geography contains 40 country and island-group outlines. These eight examples include both north–south and east–west spans. Labels identify the included territory; similarly named maps on other sites may cover a different area.

Read the axis before the shape

A long north–south country and a wide east–west country can look very different. Compare the named projected spans, rather than their filled areas.

Read the territory scope

Mainland, nearby islands and overseas territories can change an outline’s endpoints. Use the scope supplied in the question, not the broadest possible definition of a country.

How your score adds up

Each guess earns a base score from 0 to 100 by comparing your estimate with the stated reference size. The closer the ratio is to 1, the higher the score. Half-size and double-size guesses earn the same base score.

The five round weights

  1. Round 1×1
  2. Round 2×1
  3. Round 3×2
  4. Round 4×3
  5. Round 5×3

For example, 80 base points in a ×3 round contribute 240 points. Five perfect rounds total 1,000.

What the measurement includes

These maps use local equal-area projections of documented outlines. The scored reference is the outline’s stated horizontal or vertical span on that projection. It is not a travel distance, a ground-distance measurement or a comparison of land area. Generalised boundaries and the chosen island or territory scope affect the drawing. Each round identifies the axis and included territory; Sources explains the map basis.

Questions about Size It Up: Geography on Sizes.games

Can I practise Geography without a daily limit?

Yes. Geography Unlimited keeps offering new five-round games from the map category. Your completed Daily result remains separate in this browser.

Do I need an account to save progress?

No. When browser storage is available, return to the same category and mode to resume. Progress stays on that browser and device; it does not automatically sync elsewhere.

Am I guessing land area?

No. You compare a stated projected north–south or east–west span. Two places can have similar spans and very different land areas. Do not use square kilometres as the answer to a linear-span question.

Is the map span a distance along the ground?

No. It is a reference span measured on this local projected outline. It should not be read as an official ground distance, road distance or distance between two named cities.

Which islands and overseas territories count?

Follow the scope under each name. For example, the France · Europe entry includes the European mainland and Corsica while excluding overseas territories. Other entries state their own included island groups.

Why use a local equal-area map?

Projection choices affect how a map looks. A local equal-area projection provides the defined outline used here; the question still scores a labelled linear span. Equal area does not make that span a ground-distance measurement.
