# Audit Mobile Web Tap Target Dimensions Against WCAG Pointer Criteria — Free

Designing responsive web applications for touchscreen devices requires providing adequate interactive tap target sizes, yet compact mobile navigation often crowds tiny links together, causing frustrating mistaps for users with motor tremors or large fingers. Enter your interactive element dimensions, edge clearances, and WCAG criteria to audit mobile touch usability.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

Web developers, UI/UX designers, accessibility auditors, and product managers verifying WCAG mobile touch target compliance.

## What's free

- one complete unwatermarked touch-target strip run in the app
- three labeled samples and unlimited article-demo calculations
- complete result text and a user-triggered input-state link

## Optional paid add-on

**$4 one-time.**

- unlimited subsequent touch-target strip app calculations after a local convenience signal
- print the touch-target strip with visible assumptions and its safety boundary
- CSV of the displayed pixels and row workings; conditional estimate uses your manual-retyping minutes
- five local reading summaries (headline/count/time), not saved full inputs or cross-device backups

## Sources & verification

- Tool: GratisAI local-first instrument (no key, no account)
