Audit Mobile Web Tap Target Dimensions Against WCAG Pointer Criteria

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.

FIRST-LOAD

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.

Data note: The touch-target strip processes interactive button label | element width in CSS px | element height in CSS px | edge clearance spacing in px locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.

Perspective: Before: mobile website tap targets felt difficult to press without knowing why. After: CSS pixel dimensions and edge clearance spacing audit interactive elements against WCAG 2.5.8 criteria.

User interface accessibility arithmetic only, not formal WCAG compliance certification or legal accessibility warranty. Compliance audits require evaluating dynamic viewport reflow, user agent stylesheets, and user testing. Follow official W3C accessibility guidelines.

What $4 one-time adds

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

HYPOTHESIS / PROTOTYPE: $4 is a proposed one-time price for filing the touch-target strip, not a current sales offer. No measured time saving or buyer demand is claimed. The optional manual-retyping baseline above estimates one export’s retyping budget only; it does not change the calculation or guarantee savings.

Filing prototype — checkout unavailable

Checkout is unavailable. Browser-local, profile-scoped convenience gating is best-effort, not server-verified access. A URL or browser flag is not proof of payment. Clearing browser data removes local state; no account or cross-device recovery is provided.

Optional filing controls are a local prototype.

Before using the touch-target strip

The Web Content Accessibility Guidelines (WCAG) 2.2 specify clear success criteria for pointer input target sizes to ensure users with tremors, limited motor control, or large fingertips can activate controls reliably without accidentally triggering adjacent actions. Success Criterion 2.5.8 (Target Size - Minimum, Level AA) mandates that interactive pointer targets measure at least 24 by 24 CSS pixels, or provide sufficient non-interactive spacing clearance such that an imaginary 24px diameter circle centered on the target does not intersect another target. Level AAA Criterion 2.5.5 recommends a generous 44 by 44 CSS pixel target area. Enter your interactive buttons, measured widths and heights, and edge spacing clearances to audit mobile touch compliance.

Boundary and sources

Method: Determine whether the shortest element dimension (width or height) satisfies your target threshold (24px for Level AA; 44px for Level AAA).
All sample records, dates, quantities and labels are invented. No outside policy, contract, rate, clock offset, measurement or accessibility standard is represented as verified.
Google’s official pricing documentation, fetched 2026-09-30, says AI Studio is free in available regions. Optional formatting may require a Google account; manual local entry requires none. Limits can change and free-tier content may be used to improve products. Do not send private records.

Optional AI formatting, never the calculation

Manual entry completes this touch-target strip for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.

Format only these fictional or non-sensitive notes for a touch-target strip. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string", "string"]}], "setting": "string"}. The columns are interactive button label | element width in CSS px | element height in CSS px | edge clearance spacing in px; the setting is WCAG minimum touch target size threshold in CSS pixels. Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.

An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
