Graphic Design Worksheet: Pixels and Image Size

Animation and design lesson 14: Pixels and image size · Set 2 · 40 questions
TalentJR

Creator's tip (Width times height): Pixels = width × height; megapixels = pixels ÷ 1000000. Aspect ratio = width : height. 16:9 wide, 4:3 squarer, 1:1 square, 9:16 tall. Keep the ratio: a 16:9 frame 1920 pixels wide is 1920 ÷ 16 × 9 = 1080 tall. Printing: inches × pixels per inch.
