A PDF form fails screen-reader users field by field, and the count is invisible in the editor.
Turn field counts into the unlabeled-field count and a label coverage percent for the form.
Anyone preparing a PDF form for readers who use screen readers.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Count every field in the form. Include hidden and calculated fields.
Read each field with a screen reader or the tags panel. Count the fields with a real label.
Add labels to the unlabeled fields first. The label must say what the field asks.
Rerun the count after each pass. Keep the percent visible until it reaches 100.
Export the form again and test the reading order. An export can drop labels.
A form holds 30 fields and 22 carry labels. The unlabeled count is 8, and label coverage is 73.3 percent.
Use your own source and details. The example is not a record about a real person or organization.
