Check the base unit
A single spacing scale is the strongest predictor of visual consistency; using it or not is weighted most heavily.

How it works
Count value sprawl
The number of distinct spacing values relative to screen count signals how disciplined the scale actually is in practice.
Factor in alignment and responsiveness
Grid alignment and predictable breakpoint scaling round out the final spacing-health score.
Frequently asked questions
What is a "spacing base unit"?
A single number (commonly 4px or 8px) that every margin, padding and gap value is a multiple of, so spacing stays visually rhythmic across the product.
How many spacing values is too many?
A healthy MVP scale usually has 6–10 values (e.g. 4, 8, 12, 16, 24, 32, 48px). Well beyond that suggests values were chosen ad hoc rather than from a scale.
Does this tool inspect my CSS or Figma file automatically?
No. There is no file-scanning backend — you answer based on your own review, and Spacing Guard computes the weighted score from your answers.
What should I fix first from a low score?
Standardise on one base unit before addressing alignment or responsive scaling — the other two are much easier once the scale is fixed.

Figma's inspect panel shows raw pixel values but not a consolidated health score. Manual QA can catch spacing issues but rarely produces a weighted, comparable score across releases. Spacing Guard does both in under a minute.
