Multiply by 10014 December 2023
Here is a good interface principle aimed to test how scalable and well prepared your design is for real life.
If you have something listing similar entities, just multiply them by 100 and see what happens.
Say you have a text field that user should fill in and it looks neat in your design. What if you multiply number of chars by 100? Maybe single line input is not enough, maybe it will blow up or maybe you need to limit the number of chars.
Have a field with tags? What if you multiply their count by 100?
List of entries on a page, page numbers on a page, uploaded images, thumbnails, item cards, to-do list and so on... What if you multiply each one of them by 100? That is a good question to start with.
