Frequently Asked Questions

What is DPR?
Device Pixel Ratio — physical pixels per CSS pixel. Retina displays = 2 (or higher). Standard = 1. CSS sees the lower count; canvas/images need DPR scaling.
Why is screen.width sometimes wrong?
Browsers report logical (CSS) pixels, not physical. Multiply by DPR to get physical resolution. Some platforms (Mac retina) lie further to look "natural".
How accurate is PPI calc?
Browser can't know diagonal in inches — must enter manually. Once entered, math is exact. Apple lists exact PPI for each model on their site.
