Either you fit the short side or the long side but you can't match both. Which is not a perfect fit for either a 4圆 (1:1.5) or an 8x10 (1:1.25). There is one 480 inĦ40 and 160 left over (which is a third of 480), so it's 1:1.33. You ventriloquists ask, throwing your voice where we can't find it. "Fine, fine, fine, what's this got to do with my 480 x 640-pixel image," "An aspect ratio is just an awkward way of describing the The 8x10, for example, is closer to a square than the 4圆. Those are all not just different ratios but different shapes. well, the four sides of a square are all the same length. ![]() You can see by this what a square would be. How many short sides in 10? Well, it takes one 8 plus 2, which is a quarter of 8, to make 10. How about the 8x10? The short side is the 8, so 1 is 8 inches here. The mathematical description of the shape of this 4圆 print is, therefore, 1 to 1.5 or 1:1.5. To make this easy, just divide the long side (6) by the short side (4) to get 1.5. That would be one and a half (it takes one 4 with 2 left over, which is half of 4, to make 6). How many short sides are in the long side of a 4圆? Rather than divulge our colorful language for describing rectangular shapes, we'll offer simple, mathematical proof that print sizes are different shapes. ![]() They're rectangles, yes, but a 4圆 is quite a different shape than an 8x10. Because, believe it or not, not all prints are the same shape. And at the moment, we are very deep in boxes of all kinds looking for just the right shapes. We currently sit on the ANSI committee to standardize descriptive terms for the shapes of digital images. Rather than use colorful imagery (as we do in discussing the "bouquet" of wines or the "temperature" of color), we use, uh, numbers. We can clear that up right here.Īn aspect ratio is just an awkward way of describing the shape of your image. Youīut if you're as smart as we think you are, you may have been confused by all this talk about aspect ratios at your friendly online photofinisher. No yellow Dummies book for this audience. ![]() "So to minimize cropping on a 4圆 print, make sure you have
