A few weeks ago I sold some shoes on the shopping app Depop.

After I had posted the shoes, I had the option to provide the buyer with some details.

I have an iPhone SE. It’s a lot smaller than most smartphones.

This meant that I couldn’t see what details I was being asked to provide:

I could only assume the second word. My best guess was:

• Shipping provider
• Tracking number

Rather than designing the service so the second word went onto the next line, there was an ellipsis.

Which meant the design was not usable on my device. I wanted to give the buyer helpful details about shipping, but who knows if I provided the right details.

It's so important to stretch your design to make sure it works for everyone. My colleague Andrew wrote a great blog about this.

Make sure you check how your design works on different devices.
