The Mercator Projection Illusion

On standard maps, the UK often appears larger than New Zealand because the UK sits further from the equator (54°N vs 41°S). In truth, New Zealand has 10,000 more square miles of land area.

Mercator projection formulas stretch surface area proportionally to sec²(φ) = 1 / cos²(φ), magnifying landmasses drastically near the north and south poles.

Geographic Analysis: United Kingdom and New Zealand

New Zealand is 10.5% larger than the United Kingdom. New Zealand covers 103,483 square miles compared to the UK's 93,628 square miles. However, the UK has over 13 times the population of New Zealand.

About United Kingdom

The UK is home to Greenwich, the origin meridian for longitude and Universal Coordinated Time (UTC).

About New Zealand

United Kingdom vs New Zealand by the Numbers

Area: New Zealand covers 268,021 km² (103,483 sq mi), which is only 10.5% more than the 242,495 km² of United Kingdom, a difference of 25,526 km² (9,855 sq mi).
Population: United Kingdom has 13.2 times as many people (67,700,000 vs 5,120,000). That works out to about 723 people per sq mi in United Kingdom and 49 in New Zealand.
On a Web Mercator map: United Kingdom (centered near 54.5°) is drawn about 2.96× its true area and New Zealand (near -41.0°) about 1.76×. So on Google-style maps United Kingdom appears roughly 1.52 times the size of New Zealand, even though in reality New Zealand is the larger of the two.

Mercator factors use the center latitude only (area scale = 1 / cos² of latitude), so they are approximations for places that span many degrees of latitude.

How to Accurately Compare Geographic Sizes

STEP 01

Consult Geodesic Area

Use published areas from national statistics offices or census gazetteers rather than judging by pixels on a flat web map.

STEP 02

Account for Latitude

Remember that Web Mercator tiles distort areas by 1/cos²(latitude). High-latitude regions appear vastly larger than equatorial states.

STEP 03

Interactive Map Overlay

Drag one outline over the other in the true size tool; the shape is re-projected as it moves, so it keeps its real size.
