How size images we use?

[rpaganini]

Hi Cutie, Jessy and Luke.

I’m watching videos related to Beginning App Asset Design. First of all I want to congratulate you for the excellent course. U ARE THE BEST!
I have a question about graphic designer app:
If I want to develop an app that suits any type of device, what is the correct size of the images that I should use? for example what size should I use from backgroud image to adapt to an iphone SE and at the same time to an iPAD? what button image sizes should I use? Fonts and text fields automatically adapt to screen sizes? Could you help me?

Thank you very much.

Hi! Happy to hear you’re liking the course :]

Those are some really big questions! I’m sorry that the answer is “it depends…”. What image sizes you need really depends on what kind of images they are. To very broadly generalize: if you’re looking at large, raster background images, find something that works on the very largest device, first, then downsample for smaller.

For some examples of using Auto Layout to get UI elements, like text fields, to adapt to different screen sizes, check out our courses Beginning Auto Layout and Mastering Auto Layout. There’s a good example in there of a button image that resizes, too!

First of all I would like to apologize for typing your name wrong.

Catie, thank you very much for your guidance.

The autolayout part is very frustrating when it’s starting but I will review the courses and train a lot more.

It is people like you who motivate us to continue and not give up on the difficulties that appear.

Congratulations to all of the team.
