Worked example
A width of 375 px is classed as Mobile, and the sample preview box is shown at that width.
What this tool does not do / Limits
This previews sample content on this page only, at a width you choose. It does not load, render or test any outside URL, and it is not a substitute for testing a real page on real devices.
Frequently asked questions
Can I test my own website URL here?
No. This tool only previews sample content on this page at a chosen width.
Why is the preview capped?
The box is capped so it stays readable on this page; the width class still reflects the number you entered.
