![]() ![]() The first one is a measurement and the other is a proportion that can be maintained with other measurements.Īny size that has 4 units (pixels, cm, inches, whatever) on the long side for 3 units on the short side has a 4:3 ratio. While 1920×1080 has an aspect ratio of 16:9, they are not the same thing. If you’re making a video on your phone holding it vertically, it’s a 9:16 aspect ratio. Instead, a portrait-oriented photo with the same proportions would have an aspect ratio of 3:4. However, for rectangular frames, it’s important to keep a standard.įor example, if you see that an image has an aspect ratio of 4:3, you know it’s a landscape-oriented picture. In the case of 1:1, it wouldn’t matter because the image is square. The formula is Aspect Ratio = Width:Height. This is a convention so that everyone knows what you’re talking about. The aspect ratio formula is the international standard format in which the proportional relationship is expressed. Just be aware that you’ll be losing information from the edges if you decide to do this. ![]() However, you can always change your mind afterwards and crop your images to different aspect ratios in post-production. On most digital cameras and mobile devices, you can change the aspect ratio before taking the picture. Javascript Aspect Ratio Calculator.The aspect ratio is the relationship between the width and height of a frame – it has nothing to do with the size.įor example, if an image has a 1:1 ratio, it might be 500 x 500 pixels or 5000 x 5000 pixels – the aspect ratio is the same. To match the aspect ratio of the four most popular print sizes, use the following If you'd like to see at a glance the exact number of pixels your image requires That restricts the tool to a crop of that size. Select your Crop or Rectangular Marquee Tool and enable the Fixed Size option, entering the pixels or inches of your target print size. We thought we just heard a little voice somewhere ask, "How do you make sure?" Ventriloquists can be a tough audience. And if you want an 8x10 print, make sure you have a 1:1.25 aspect ratio. If you want a 5x7 print, make sure you have a 1:1.4 aspect ratio. So to minimize cropping on a 4圆 print, make sure you have a 1:1.5 aspect ratio (and expect a little trimming). Exactly 4圆, 5x7 or 8x10 (which conveniently slip right into inexpensive pre-built frames). Ofoto uses a "zoom-and-trim technique similar to what a traditional photo lab would use, which automatically adjusts the image's dimensions to fit the desired print size." Basically that means they print the image large enough so that it spills over all four sides and then they trim to size. 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.
