Keep text and controls usable when readers increase spacing

Custom spacing preferences can make lines or words taller than a tightly designed container allows. Visitors may encounter overlapping labels or missing lower lines even though standard text looks fine.

What to change

Ask your supplier to demonstrate the page with wider text spacing and make boxes adapt so labels, instructions and actions remain complete.

A worked example

Illustrative example

A two-line button label becomes three lines under increased spacing, but the button grows and the next control moves down without overlap.

Why this matters to your practice

Some visitors increase the space between letters, words or lines to make reading easier. The design should accommodate that choice, including in compact controls. Ask your supplier to demonstrate a recognised spacing check on a real form and service page. You do not need to set the technical values yourself. Look for ordinary consequences: a label cut in half, a message covering a button, or the bottom line of an instruction disappearing inside a fixed box.

A practical review example

A two-line contact button may become three lines when someone increases spacing for easier reading. The useful result is a taller button and a sensible gap before the next control, not hidden words or overlap. Ask the supplier to demonstrate a recognised spacing check across a form, menu and card collection. Complete an action while the adjustment remains enabled. A screenshot showing ordinary paragraphs still readable does not establish that compact choices and correction messages remain usable through the full task.

How to check the result

Accept when the tested spacing changes do not remove information or functionality, and affected components adjust without forcing smaller text.

A mistake to avoid

Checking paragraph text alone misses many failures in compact controls, badges and input labels.
