We pull out yesteryear's P20 Pro and put it next to Huawei's latest camera prodigy for some quick comparisons:

The P30 Pro (left/bottom) is 3 mm taller, 0.61 mm thicker, and a little less wide (0.5 mm) than its predecessor.

Despite the home button and earpiece speaker grille vanishing behind the screen, the P30 Pro has grown taller.

The power and volume buttons are still where they were last year.

Along the bottom edge of the phone we see the USB-C port remains, while the four microphone holes mirroring the speaker holes have been cut down to one to make room for the SIM card slot.
