Problem with sizing in Photoshop

I'm guessing that you several years ago had a standard resolution monitor (like 1920 x 1080), but you now a high resolution monitor, maybe 3840 pixels or more on the long side.

If the new monitor has the same physical dimensions as your old one, images will display at exactly half the physical size when screen resolution is doubled, because the pixels are 50% smaller.

Web browsers and image viewers will enlarge images to 200% when detecting a high resolution screen, but Photoshop cannot do this, it has to display correctly, one image pixel for one screen pixel at 100% view.

To view images the same way other applications do in Photoshop, go to View > 200%.

Note– Images for the web, resolution is irrelevant.

Double check your settings in Image Size.

Make sure your units of measure is correct.
