About AirScale

Every day you get five comparisons. Each one shows a reference at its true size and a target you have to resize until it looks right. Most of them involve aircraft, and they get harder as you go: the last round always puts two aircraft of similar size head to head.

Scoring

Each round is worth up to 100 points. Error is measured on a log scale, so drawing something twice too big is exactly as bad as drawing it twice too small. Anything 2× off or more scores zero. The maximum is 500.

🎯 95+ · 🟩 80+ · 🟨 60+ · 🟧 30+ · 🟥 below 30

Silhouettes and dimensions

All drawings use the same scale: one unit in the drawing is one meter. Aircraft dimensions come from manufacturer airport planning manuals and official fact sheets. Drawings marked draft are temporary and are being replaced with tracings from those documents.
