Use Chrome's current-site zoom when one website is difficult to read but others are already comfortable. Keep that choice separate from the default zoom used more broadly.
Open the site-specific control
In Android Chrome, open More, Settings, Accessibility to enable the zoom option in the main menu. On the website, choose More, Zoom and adjust it. Chrome saves this choice for that site rather than applying it to every other site. The separate default setting has a different scope. See Google's Chrome page-zoom instructions.
Before changing it, choose a public reading page and note the original setting. Identify a paragraph, its right edge and a long button label. These are specific places to check after enlargement; merely noticing larger letters does not establish that the page is still usable.
Compare two hypothetical websites
Suppose site A has small text while site B is already readable. Enlarge A using the current-site control, then revisit B without changing its setting. Write separate notes: “A: enlarged for reading” and “B: kept at its previous choice.” This is a scope test, not a recommendation for a particular zoom number.
Return to A and check the full paragraph, rightmost text and complete button label. If the label is now clipped, record that alongside the readability improvement. Try a smaller change or restore the initial choice rather than treating the largest letters as the best outcome.
Recognise what zoom cannot recover
Zoom cannot supply a sentence that was never included or guarantee that an awkward layout will resize correctly. In a hypothetical report, “text larger but final label words hidden” is a more useful description than “fixed”. Keep any clipping problem unresolved until the complete wording can be read.
