Use this free pixel circle generator to draw mathematically consistent circles on a square grid. Choose hollow rings or filled disks (3–128 px), tune thickness and ASCII characters, preview on a live canvas, then copy patterns or x,y coordinates for sprites, engines, and tile maps.
Pair with the Minecraft Circle Generator, Pixel Art Generator, and Mandala Generator for circular creative workflows.

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

Circles on a pixel grid are never perfect curves — they are approximations built from square cells. A generator applies consistent math so every arc step looks intentional instead of hand-tweaked.
This tool targets screen pixels and sprite coordinates, not Minecraft blocks. Export ASCII for notes or coordinate lists for code — then paint colors in your editor of choice.
Three steps from blank grid to exportable circle data.
Choose how many pixels wide the square canvas is (3–128) — larger values give smoother curves.
Use hollow mode for outlines and UI rings, or filled mode for solid disks and stamps.
Copy the ASCII grid or x,y coordinate pairs for engines, docs, and pixel editors.
Six export surfaces update live as you change diameter, mode, or characters.
Scaled visual with optional per-pixel grid lines and adjustable cell size.
Monospace text grid using your chosen filled and empty characters.
x,y pairs with top-left origin — one coordinate per filled pixel.
Total pixels set — useful for sprite budgets and collision mask sizing.
Effective radius in pixels for layering smaller circles into spheres.
Block, hash, and square tile presets plus custom fill and empty chars.
Pick the mode that matches your art or game system before exporting.
Outline-only circles with thickness 1–64 — UI borders, shields, and rims.
Solid pixel circles — coins, planets, buttons, and stamp brushes.
Hollow mode ring width control so small diameters stay readable.
Rough guidance for 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.
This tool uses top-left x,y pixel coordinates and a live canvas — ideal for sprites, UI, and engine prototypes. One pixel equals one screen cell, not necessarily one Minecraft block.
For in-world builds with relative commands and block-scale ASCII (■ and ·), use the Minecraft Circle Generator with diameters up to 256 blocks.
Hand-drawn circles on low grids often look lumpy at small sizes. Consistent algorithms keep collision masks, UI rings, and roguelike rooms readable when scaled down to 16×16 sprites.
Coordinate export saves time in Godot, Unity tilemaps, and spreadsheet-based level tools — paste once instead of clicking each cell.
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.
From tiny icons to large tile regions — preview scales automatically.
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.
Runs locally in the browser after load — no server round-trip per change.
Circles show up everywhere in digital art and game tooling.
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 caverns and room outlines using text-friendly symbols.
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.
