The print size based on the current resolution. It controls the size that your image will print, and nothing else: And that's all that image resolution does. And here we see that sure enough, at a resolution of 300 pixels/inch, my image will print 20.053 inches wide and 13.387 inches tall. To view the current print size of your image, change the measurement type for the Width and Height from Pixels to Inches. Viewing the current print sizeĭirectly above the Resolution value in the Image Size dialog box are the Width and Height options.

A height of 4016 pixels divided by 300 pixels/inch means that the height of my image, when printed, will be roughly 13.387 inches. And we can do the same thing with the height. So with my image, a width of 6016 pixels, divided by the resolution value of 300 pixels/inch, means that my image will print at a width of roughly 20.053 inches. To figure out the actual print size, we just divide the width and height of the image, in pixels, by the resolution value. It also means that 300 pixels from the height of the image will be packed into every inch of paper from top to bottom. How image resolution affects print sizeįor example, a resolution of 300 pixels per inch means that 300 pixels from the width of the image will be packed into every inch of paper from left to right. And lower resolution values pack fewer pixels per inch, giving us a larger print size. Higher resolution values pack more pixels into a linear inch, resulting in a smaller print size. The Resolution value in Photoshop's Image Size dialog box sets the number of pixels from your image that will print per linear inch of paper. Image resolution does one thing and one thing only it controls the size that your image will print. So let's start by learning what image resolution really means. So what exactly is image resolution, and what does this option in the Image Size dialog box actually do? There's a lot of confusion out there regarding the resolution value, especially when it comes to uploading images to the web. See Expressions for field input for details.The current image resolution. Instead of adding absolute input values you can enter expressions instead. Available as 'separable' and 'non-separable' the latter gives marginally better results, but is slightly slower than 'separable'.

Lanczos 3-complex algorithmic resampling that offers sharp results but with the longest processing time.

Resampling is smoother than Bilinear but has a slower processing time.

Bicubic-algorithmic resampling for use when upsampling images.

Bilinear-algorithmic resampling for use when downsampling images.

Nearest Neighbor-simple resampling which has the fastest processing time.

The following resample settings are available: Select a Resample method from the pop-up menu.

Rulers will update to the new measurement unit. (Optional) Select a different measurement unit from the Units pop-up menu.To resize the width and height independently, click the lock icon (to unlock) between the Size boxes.Enter your new document dimensions in the Size boxes-left box for width, right box for height.Ensure the Resample option is switched on.You will see no change in the image on the page as this procedure only affects the image's metadata.

Set higher values (e.g., 300dpi) for professional printing.

Change the DPI to control the number of pixels (dots) which will be printed per inch when your document is printed.

Ensure the Resample option is switched off.

From the Document menu, select Resize Document.

Reduce an image for on-screen display and to optimize file size.

Enlarge an image to specific dimensions in preparation for printing.

Select from a variety of interpolation methods (see note below).

Maintain the image's aspect ratio or resize unconstrained.

When you resample an image, you have the option to: This will also decrease the image's file size.

Decrease the number of pixels in an image (i.e compress it) to make its overall pixel dimensions smaller.

This will also increase the image's file size.

Increase the number of pixels in an image (i.e stretch it) to make its overall pixel dimensions bigger.

The image's pixel dimensions remain unaffected. Scaling will embed a specific print resolution into an image's metadata to force it to print at a specific dpi (e.g. These can be undertaken independently or simultaneously. You can change the 'size' of an image by scaling or resampling it. In Affinity Photo there are options to change a document's or image's pixel dimensions and/or print resolution.
