Logo Size Variants Calculator

Work out logo size variants instantly with clear inputs, formula shown and shareable results.

About Logo Size Variants Calculator

Each variant is the previous width multiplied by the reduction ratio, giving a geometric set of sizes rather than evenly spaced ones. A geometric series keeps the visual step between variants constant, which is what stops a logo set having two sizes that look almost identical.

Formula

Variant widths

width at step k = primary width x ratio ^ k

Worked example

With the default values below, Logo Size Variants Calculator returns Smallest variant width of 76. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Logo Size Variants figure worked out?

width at step k = primary width x ratio ^ k. Each variant is the previous width multiplied by the reduction ratio, giving a geometric set of sizes rather than evenly spaced ones.

Why does this matter?

A geometric series keeps the visual step between variants constant, which is what stops a logo set having two sizes that look almost identical.

What do I need to enter?

Enter primary logo width, number of smaller variants, reduction ratio per step. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
