Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/no-undersized-icon-button. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

const A = () => (
  <button aria-label="Close" className="size-6 !size-4 p-0">
    <CloseIcon />
  </button>
);
const B = () => (
  <button aria-label="Close" className="size-4 !size-6 p-0">
    <CloseIcon />
  </button>
);
const C = () => (
  <button
    aria-label="Close"
    className="!size-6 p-0"
    style={{ width: 20, height: 20, padding: 0 }}
  >
    <CloseIcon />
  </button>
);

Corrected pattern

const A = () => (
  <button aria-label="Close" className="size-6 p-0">
    <CloseIcon />
  </button>
);
const B = () => (
  <button aria-label="Close" className="size-4 !size-6 p-0">
    <CloseIcon />
  </button>
);
const C = () => (
  <button
    aria-label="Close"
    className="!size-6 p-0"
    style={{ width: 20, height: 20, padding: 0 }}
  >
    <CloseIcon />
  </button>
);

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/no-undersized-icon-button diagnostic in the current repository. Required change: - Make the button at least 24 by 24 CSS pixels, or provide enough surrounding target spacing to satisfy the WCAG exception.

Reference transformation:Before:

const A = () => (
  <button aria-label="Close" className="size-6 !size-4 p-0">
    <CloseIcon />
  </button>
);
const B = () => (
  <button aria-label="Close" className="size-4 !size-6 p-0">
    <CloseIcon />
  </button>
);
const C = () => (
  <button
    aria-label="Close"
    className="!size-6 p-0"
    style={{ width: 20, height: 20, padding: 0 }}
  >
    <CloseIcon />
  </button>
);

After:

const A = () => (
  <button aria-label="Close" className="size-6 p-0">
    <CloseIcon />
  </button>
);
const B = () => (
  <button aria-label="Close" className="size-4 !size-6 p-0">
    <CloseIcon />
  </button>
);
const C = () => (
  <button
    aria-label="Close"
    className="!size-6 p-0"
    style={{ width: 20, height: 20, padding: 0 }}
  >
    <CloseIcon />
  </button>
);

Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Use existing brand assets, product facts, content, and design tokens. - Do not invent claims, customer data, typefaces, or artwork. - Preserve accessible names, focus order, keyboard behavior, and touch access not targeted by this rule. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.
