Tanzania on five projections
Tanzania covers 936,892 km² of ground. Mercator draws it 1.01 times over. Area and shape readings on all five projections, each one measured.

On five projections
Each number is measured against its own projection's equator, not against another projection. These five rows do not share an axis - they are five answers to the same question: what did this map give up to lay this place flat?
| Projection | Area distortion | Shape distortion |
|---|---|---|
| Equirectangular | 1.01 | 1.01 |
| Mercator | 1.01 | 1.00 constant |
| Natural Earth | 1.01 | 1.15 |
| Equal Earth | 1.00 constant | 1.34 |
| Gall-Peters | 1.00 constant | 1.98 |
Mercator inflates it most, 1.01 times over. Gall-Peters stretches it most: its long axis is 1.98 times its short one.
The same size, drawn otherwise
Nothing in the catalogue is close to Tanzania's area at a far enough latitude to be worth the comparison.
Bigger than the map admits
Mercator draws nothing larger than Tanzania smaller than it.
On an equal-area projection this section is empty, for every object there is. An equal-area map draws in proportion to true area, so it cannot draw a larger thing smaller. That is a definition, not a coincidence.
