WORLD PLANNING

Tilemap & World Size Calculator

Convert tile dimensions into pixel canvas size, tile counts, and a simple index-memory estimate.

TILE DIMENSIONS

Estimate map size

Browser-only
Total tiles
Pixel canvas
4-byte index estimate
The 4-byte index estimate uses binary MB (MiB): total tiles × 4 ÷ 1,048,576. It excludes textures and other runtime memory. Use chunking for large worlds. Keeping logical tile dimensions separate from render texture dimensions helps streaming and memory budgets.

Tilemap and world size guide

World dimensions affect streaming, collision, pathfinding, texture memory, and how long movement takes. Measure them before building content around an arbitrary map size.

Use the result as a balancing or prototyping starting point, then validate it against your own game data and playtests.

Plan chunks and coordinate space

Separate logical tile coordinates from render pixels. Large worlds are easier to stream when they are divided into predictable chunks with clear origin and boundary rules.

A practical production check

Record the assumptions behind the estimate, test a small and a worst-case scenario, then compare the result with a profiler, playtest, or representative content sample. This turns a one-off number into a repeatable design decision.

Prototype first, tune second

A calculator or generator can expose relationships quickly, but the final values should be checked against player experience, content cadence, and the rest of your economy or combat system.

Frequently asked questions

Does this replace playtesting or profiling?

No. It provides a fast, repeatable baseline so testing starts from informed numbers rather than guesses.

Can I use this for a shipped game?

Yes, as a planning and comparison aid. Confirm critical budgets with measurements from your target hardware, network conditions, or production data.

Does my data leave the browser?

No. These tools run locally in your browser.
