33 File resolution Determine standard viewing distance 1.5 x diagonal Measure or math (sorry!) 12 x 40 33

34 File resolution Width times width (width squared) 40 x 40 = 1600 Height times height (height squared) 12 x 12 = 144 Add the two values = x 40 34

35 File resolution Width times width (width squared) 40 x 40 = 1600 Height times height (height squared) 12 x 12 = 144 Add the two values = x 40 35

36 File resolution Width times width (width squared) 40 x 40 = 1600 Height times height (height squared) 12 x 12 = 144 Add the two values = x 40 36

37 File resolution Hit the square root key = 42 - The diagonal Multiply by x 1.5 = x 40 37

38 File resolution Hit the square root key = 42 - The diagonal Multiply by x 1.5 = x 40 38

39 File resolution Standard viewing distance 63 feet = 756 inches File resolution 3438 Std. Viewing Distance = 5 ppi 12 x 40 39

40 File Resolution 5 ppi??? 40

41 File Resolution 5 ppi??? 41

42 File Resolution 5 ppi??? 42

43 File Resolution 8.5 x 8.5 = x 11 = = 192 SVD = = 245 ppi 133 x 1.5 or 2 = 200 to 266 ppi 43

44 Large-format file resolution Check with your printer 9 ppi typical 8 to 25 ppi common 12 x 40 44

45 File resolution spreadsheet 12 x 40 45

46 Document size limitations Adobe Illustrator x (18 feet) Adobe InDesign 216 x 216 CorelDRAW 150 x 150 (yes, feet!) 46
