Draw a Perfect Heart — Freehand Heart Test
The Art and Science of Drawing a Perfect Heart
The draw a perfect heart challenge tests something harder than most people expect. A mathematically perfect heart follows a specific parametric equation — 16sin³(t) for width and a cosine sum for height — creating the iconic two-arc top and pointed bottom. Our scoring algorithm fits your freehand drawing to this ideal curve, measuring how closely each point you drew matches the theoretical heart shape, how symmetrically you divided left and right, and whether you closed the loop.
In our heart drawing test, the top dip and the bottom point are the two hardest features. The center top requires two curves to meet cleanly and symmetrically — most people draw one side slightly higher or rounder than the other. The pointed bottom requires the two long curves to converge sharply. Professional illustrators use a single fluid motion — starting at center top, sweeping one arc, and returning up the other side — to achieve the smoothest results. Try on mobile for a different feel: touch input often produces softer, more natural curves.
