Calculated pixel dimensions (in gray text) are excessively shown out to a few decimal places (even if pixels cannot have fractions), to show that the megapixels come out exact, matching the same as entered. The first option (Megapixels) calculation is the regular option.There are two calculator options, and the results for each case are: But dimensions of images cropped or resampled in your editor have low odds to be evenly divisible by 8. Precise megapixels and aspect values obtained from the actual camera image pixel dimensions should match it, but camera specifications otherwise round them. But resampled or cropped images might have any dimensions, likely Not divisible by 8.ĭiv8 - Images resized in photo editors can be any dimensions, but camera sensors actually use pixel dimensions which are evenly divisible by 8, no doubt to match JPG 8x8 compression blocks (I'll call that value Div8 here). Cameras create pixel dimensions evenly divisible by 8 (I will call it Div8, and is only size shown if already Div8 is specified). One pixel difference of width might affect a few thousand rows of height.ģ. Dimensions rounded to whole pixels, necessary for real pixels, but which changes megapixels a little. Exact computed dimensions (matches specified megapixels exactly, even if pixels cannot be fractional).Ģ. Three values of pixel dimensions may be shown, in the order of:ġ. Your results will come out closer if entering your actual real numbers instead of the rounded camera specifications.īut there are ifs and buts about everything, so trying to explain why the result megapixels may not exactly match your specified megapixels. Megapixels use the conventional 1000 = 1K, and NOT the 1024 = 1K used by memory chips.Īspect Ratio is exactly computed by image dimensions in pixels, Aspect Ratio = Width / Height. Megapixels are exactly computed by image dimensions in pixels, megapixels = Width × Height. The calculator will show the precise format, as like 1.3315:1 format. Screen Solutions International strives to maintain a healthy appetite for the unique and challenging.Aspect ratio 4:3 is 4/3 = 1.333, which can be entered here as:Ĥ:3 or 1.333:1 or 1.333, or as 1.338 if and when more precise.
