It depends on what you use it for. If you use it for some social media and texting, go for a smaller phone.

If you consume visual media go for a bigger one. You’ll ruin your eyes.

Or get a smaller phone and an iPad.

I currently have the XS and will move to the 14 Pro soon, I hope, due to battery reasons, poorer eyesight, and the camera.

Nevertheless, I believe a phone should easily fit in a front pocket and not be huge. For research or visual media I’ll use my iPad or PC.
