A menu may look fine on a wide desktop and a small phone while failing in between. Tablet widths and larger text settings can expose assumptions about how much room each navigation item needs. Test the real labels and controls instead of selecting a breakpoint only because it is common.
Measure the Occupied Space
Include the logo, brand text, navigation labels, contact button, gaps, and container padding. Check whether a dropdown trigger adds width or whether long service names wrap unexpectedly. A header that barely fits at one size can break when the browser uses different font metrics. Identify the crowded component before shrinking every label.
Switch Layouts Before Collisions
Choose a compact menu layout at the point where the full navigation stops working comfortably. Keep touch targets usable and make open and close states clear. Ensure a Services submenu works with a click or keyboard action rather than depending only on hover. The compact layout should retain every service link that exists on desktop.
Test the Complete Interaction
Open the menu, open Services, choose a destination, and return using the browser controls. Check outside-click and Escape behavior where supported. Verify that the open panel fits the available screen height and can scroll when necessary. Finally, confirm that changing orientation does not leave the menu stuck or cover the page with an invisible overlay.
What to Check
- Measure the logo, controls, and real labels.
- Change layout before items collide.
- Keep all service destinations available.
- Test open, close, scroll, and orientation changes.
