What Is a Logo Scale Test?
A logo shows up at wildly different sizes depending on where it's used — from a tiny 16px favicon to a huge outdoor banner spanning thousands of pixels. This calculator takes a minimum size, a maximum size, and a step count, then generates an evenly scaled list of sizes to test in between.
Why Use a Geometric Ratio?
Splitting sizes evenly by addition (say, +16px each step) barely changes anything at small sizes and creates huge jumps at large sizes. A geometric progression (a fixed multiplier) keeps the perceived size difference consistent at every step, making it much easier to spot exactly where legibility breaks down.
What to Check at Each Size
At every step, check whether text turns into a smudge, whether fine details in the symbol disappear, and whether color contrast holds up. For tiny areas like favicons or app icons, it's common to prepare a simplified symbol-only version that drops the wordmark entirely. Keep this size list handy in your brand guideline document too.
Frequently Asked Questions
5 to 7 steps usually cover everything from favicon to large banner sizes. Use up to 10 steps for more thorough legibility testing.
Perceived size differences scale with ratio, not absolute pixels. A geometric progression keeps each step feeling equally different, while equal increments crowd the smaller sizes together.
