What to change
Ask your supplier to keep text readable and actions stable before and after the preferred typeface becomes available, including on a first visit.
A worked example
Illustrative example
A service heading changes typeface without pushing its booking link beneath the visitor's finger or making a previously visible instruction disappear.


Why this matters to your practice
A chosen typeface may arrive after the rest of the page, particularly on a first visit or slower connection. If its arrival moves a booking button under someone's finger, a visual detail has become an interaction problem. Ask your supplier to demonstrate that first-visit experience. The practice should still be recognisable and the text readable if the preferred font never arrives. Judge the stability of the actions and instructions, rather than whether a fast office connection hides the change.
A practical review example
A service heading may change line length when its chosen font arrives, pushing the contact link down just as someone taps. Ask your supplier to demonstrate the first visit on a slower connection and try the action during that transition in a test. Then review the page when the font never arrives. The fallback should still provide complete wording and usable controls. A fast repeat visit on an office browser can hide this issue because the typeface may already be saved locally.
How to check the result
Accept when delayed or failed font loading preserves readable content and avoids material movement of controls during ordinary use.
A mistake to avoid
A fast local preview often reuses cached fonts and cannot reveal the first-visit behaviour that needs checking.
