Draw mathematically consistent circles on a square pixel grid. Choose hollow rings or filled disks, tune thickness, preview on a live canvas, then copy ASCII art or coordinate lists for sprites, engines, and tile maps.

Origin (0,0) is the top-left pixel. X increases right; Y increases down — standard for pixel art and screen coordinates.

Three steps from blank grid to exportable circle data.
Choose how many pixels wide the square canvas is — larger values give smoother curves but more pixels to manage.
Use hollow mode for outlines and UI rings, or filled mode for solid disks and stamps.
Copy the ASCII grid into docs or chats, or copy coordinate pairs for engines and spreadsheets.
Built for pixel artists, hobbyists, and developers who need clean circular grids fast.
See the circle scaled to your screen with optional pixel grid lines for alignment checks.
Switch between full disks and adjustable-thickness rings for outlines and borders.
Swap block, hash, or tile-style characters so exports match your notes or toolchain.
One-click copy for text patterns and newline-separated x,y coordinate lists.
See how many pixels are set and the effective radius at a glance.
Runs locally in the browser after load — no server round-trip per change.
Circles show up everywhere in digital art and game tooling — here are a few popular ones.
Sketch circular shields, coins, planets, and rims without guessing arc steps by hand.
Drop coordinate lists into prototypes for collision masks, spawn rings, or AoE indicators.
Prototype circular frames, avatars, and progress rings on a strict pixel grid.
Plan round rooms, islands, and arenas on square tiles or grid paper.
Show how Cartesian rows and columns map to screen pixels in classrooms or workshops.
Generate circular caverings and room outlines using text-friendly symbols.
Rough guidance for choosing diameters when you care about smoothness versus file size or build time.
Icons, bullets, tiny planets, and UI dots where every pixel counts.
Character-scale props, ability range rings, and readable HUD frames.
Big environments, splash art guides, and detailed tile regions with gentle curves.
Small habits that keep circles looking intentional on low-resolution grids.
Odd sizes (9, 15, 21…) give a single center pixel that simplifies mirroring and rotation.
On small canvases, increase ring thickness so the curve stays visible when scaled down.
If your tool uses bottom-left origin, flip Y when importing coordinates.
Paste ASCII into editors that support monospace fonts so columns stay aligned.
Use several diameters in sequence to approximate spheres and domes in voxel style.
For exact block placement in Minecraft, cross-check with the Minecraft Circle Generator for command-friendly output.
