Watching PDF Lookbooks and Size Charts for Access Problems
PDF lookbooks and size charts often ship untagged and unreadable to assistive technology. How to watch them, and when an HTML page is the better answer.
Somewhere on most apparel and home goods sites sits a PDF doing quiet damage. It holds the size chart, the care guide, or the season lookbook, and it was exported straight from a design tool with no tags, no reading order, and text that a screen reader reads as a jumble or not at all.
PDFs drift out of attention because they are files, not pages. Nobody gets an alert when a new version is uploaded, and the old checks nobody ran are not run again. Watching them needs a deliberate list.
Inventory every PDF that carries product facts
Start by listing PDFs linked from product, collection, and help pages, then sort them by what they carry. Anything holding measurements, care instructions, warranty terms, or safety information is product fact, and it needs to be readable by everyone who buys the item.
You will usually find duplicates and stale versions in that inventory. Removing old files and pointing links at one maintained version shrinks the watch list and the shopper confusion at the same time.
Test reading order, not just openability
A PDF that opens is not a PDF that works. Open each priority file with a screen reader or the built in reading check in your PDF tool and listen to the order. Headings should come before the tables they describe, and table cells should read with their headers.
Untagged exports fail this test immediately. The fix is either a properly tagged export from the source file, with real heading and table structure, or moving the content to HTML, which is usually faster and easier to maintain.
Prefer HTML for charts and guides
Size charts especially belong in HTML. An HTML table can be read cell by cell, searched, zoomed, and updated in minutes when measurements change. A PDF chart can do none of that gracefully, and every correction means a new export and a new upload that may break existing links.
Lookbooks are a closer call, since they are visual by nature. If a lookbook stays PDF, add a tagged structure, alt text for key images, and an HTML summary page that carries the product names and links in plain text.
Recheck after every seasonal upload
New seasons mean new files. Add PDF checks to the seasonal launch list: inventory changes, reading order spot checks, and link checks from the pages that reference them. Assign the check to the person uploading the file, while the source is still open.
Keep file names stable where you can. Replacing a file at the same address preserves bookmarks and help center links, and your watch log stays meaningful month to month.

Frequently asked questions
How can I tell if a PDF is accessible?
Run the accessibility check in your PDF editor and read the file with a screen reader. A tagged PDF has headings, lists, and tables marked as structure, and it reads in a sensible order. Untagged design exports usually fail both tests.
Why are PDF size charts such a problem?
Charts are tables, and untagged PDFs lose the link between a cell and its row and column headers. A screen reader may read a string of numbers with no context. An HTML table preserves those relationships and is easier to update.
Does a lookbook really need to be accessible?
If it is part of how you sell products, yes, at least in summary. Provide alt text or an HTML companion that names the products shown and links to them, so shoppers who cannot see the imagery still get the information and the route to buy.
How often should PDFs be rechecked?
Check whenever a file is replaced, and do a full inventory review each season. PDFs change through uploads rather than page edits, so tying checks to uploads and seasonal launches catches most drift.
