Numbers spelled out

Forbidden
"eight hundred and ninety nine designers"
Instead
"899 designers". Numerals have a different shape to letters, so they are faster to find and read, and anyone looking for a figure expects a figure.

What this rule looks like

Forbidden
Instead

Why this rule

Format consistently: 1,000 not 1000. For very large numbers, mix numerals and words — 1 billion, not 1,000,000,000 — so nobody has to count digits.
