How many tennis courts laid end to end match a Quidditch pitch?
A Quidditch pitch measures 152.4 m (500 ft) end to end, and a tennis court measures 23.8 m (78 ft) end to end. A Quidditch pitch comes to 6.41 times the length of a tennis court, a difference of 128.6 m (422 ft). Take 6 tennis courts laid end to end and you reach 142.6 m (467.9 ft), still 9.78 m (32.1 ft) short of a Quidditch pitch; one more would overshoot by 14 m (45.9 ft). A Quidditch pitch is written in hundreds of metres and a tennis court in tens of metres, a whole band of scale apart.

Both figures, Quidditch Pitch and Tennis Court, come from the Size It Up measurement set, one real-world size and one measured axis per object, last checked in September 2026; outline provenance is listed on the sources page.
Why this one is hard to judge by eye
A Quidditch pitch has never been measured, only stated: the figure comes from its source and moves when the source is redrawn, while a tennis court can be checked with a tape, so this pair sets a decision against a measurement. A Quidditch pitch is drawn about 6.41 times as wide as a tennis court as well as 6.41 times its length, so the area it takes in the frame grows faster than the figure anyone quotes. Nothing this size arrives at the eye whole: a Quidditch pitch reaches you as a small angle from wherever you can stand back far enough to see it, and the brain fills the rest in from what it expects, which is how 128.6 m of difference goes unnoticed.
What each figure covers
Quidditch Pitch. The pitch is stated at five hundred feet long and a hundred and eighty wide in the source material. It is one of very few invented sports grounds with published dimensions.
Tennis Court. A tennis court is measured baseline to baseline. The doubles width is wider than the singles width, but the length never changes.
A Quidditch pitch and a tennis court are both quoted as a length, which is what makes the ratio above a like-for-like figure.
What else is about that size?
Measured the same way, Quidditch Pitch at 152.4 m sits within a quarter of Typhoon Class Submarine at 175 m, Azzam at 180.6 m and Sydney Opera House at 183 m. Tennis Court at 23.8 m has Diplodocus at 25 m, James Webb Space Telescope at 21.2 m and Blue Whale at 27 m for company, within a quarter. Swapping any of those in for a Quidditch pitch would move its ratio to a tennis court by less than 25%.
