Actually, the TMS9918 has a 240x192 text mode with 40x24 characters of 6x8 each and several 256x192 graphics modes with 32x24 characters of 8x8 each. This is always fewer than Apple II's 280 pixels per line.

So, measured in NTSC color pixels, it's 320 wide (40x8) compared to 280 (40x7) for the Apple II. This image (white text on a blue background) shows how the 9918's native pixels line up with the NTSC color burst frequency: https://imgur.com/rGcRpw0 https://imgur.com/rGcRpw0
