Writing Accessible Math Labels

Writing Accessible Math Labels records a distinct W3C-supported accessible-naming task and keeps implementation mechanics outside the writing guidance.

Quick answer

Use a concise text representation or identifying name that communicates the mathematical expression or its established purpose without adding unrelated prose.

Key details

Core IssueW3C APG recommends an accessible name for math when a name is needed to represent or identify the expression, including cases where presentational descendants would otherwise lose semantic detail.

Important caveats

Scope Boundary

This page covers wording an accessible name for a math role; MathML authoring and mathematical notation semantics remain separate implementation topics.

Further guidance

Content

Write the accessible name to represent the expression faithfully; when a familiar named expression is the intended identity, use that established name consistently.

Purpose

A useful math name gives assistive-technology users a meaningful text representation or identity for the expression.
