Click any of these topics to learn more about the dissimilar aspects of image size and resolution:
Printed image resolution
are the full number of pixels along the width and top of an image.
is the number of image pixels assigned to each inch when an image is printed – measured in pixels per inch (ppi). Thus, the more pixels an epitome has per inch, the greater will exist its resolution. And, a high-resolution image volition produce a amend quality printed output.
When irresolute the
Resolution, remember that the image data remains constant until you resample it. If you modify the resolution, the width and height will alter accordingly to maintain the same amount of image information.
Note the relationship between
To navigate to the Epitome Size dialog box, follow these steps:
pick checkbox is checked by default. Use it to adjust the dimensions of your image.
TheImage Size dialog box displays the many interpolation options that yous tin use to make images await crisp and sharp even after enlarging them.
To your left is the preview window which displays a alive preview of what the paradigm will look like based on the called settings. To your right are the settings themselves.

pick, which volition help yous with default interpolation. For more refined control, you can opt for the other options also. Each one of these options is designed for specific prototype enlargement or reduction workflows.
To quickly display the current epitome size, use the data box at the bottom of the document window.
Then you can position the mouse over the file information box and concord down the mouse left push button.
Monitor resolution is measured in pixels. If the resolution of the monitor and pixel dimensions of the epitome are the aforementioned size, the image volition fill the screen when viewed at 100%.
Factors that decide how large an image appears on screen
- Pixel dimensions of your image
- Size and resolution settings of your monitor
In Photoshop, you tin change the onscreen image magnification, and then you tin hands work with images of whatever pixel dimensions.
When preparing images for onscreen viewing, you should consider the lowest monitor resolution that your photo is likely to be viewed on.
The file size of an prototype is the digital size of the image file, measured in kilobytes (G), megabytes (MB), or gigabytes (GB). File size is proportional to the pixel dimensions of the paradigm. Images with more pixels may produce more particular at a given printed size, only they require more disk infinite to store and may be slower to edit and print. Image resolution thus becomes a compromise between image quality (capturing all the data you need) and file size.
Another factor that affects file size is file format. Because of the varying pinch methods used past GIF, JPEG, PNG, and TIFF file formats, file sizes tin can vary considerably for the aforementioned pixel dimensions. Similarly, color bit-depth and the number of layers and channels in an image touch file size.
Photoshop supports maximum pixel dimension of 300,000 by 300,000 pixels per image. This restriction places limits on the print size and resolution bachelor to an epitome.
Printer resolution is measured in dots per inch (dpi). The college the dpi, the finer the printed output you lot’ll become. Most inkjet printers have a resolution of approximately 720 to 2880 dpi.
Printer resolution is different from, but related to, paradigm resolution. To impress a high-quality photograph on an inkjet printer, an image resolution of at to the lowest degree 220 ppi should provide skilful results.
is the number of printer dots or halftone cells per inch used to impress grayscale images or colour separations. Also known equally
line screen, screen frequency is measured in lines per inch (lpi), or lines of cells per inch in a halftone screen. The higher the resolution of the output device, the finer screen ruling yous can use.
The relationship betwixt image resolution and screen frequency determines the quality of detail in the printed image. To produce a halftone image of the highest quality, you generally use an image resolution that is most 1.5 to 2 times the screen frequency.
With some images and output devices, a lower resolution can produce good results. To determine your printer’s screen frequency, check your printer documentation or consult your service provider.
Some imagesetters and 600‑dpi laser printers employ screening technologies other than halftoning. If you are printing an image on a nonhalftone printer, consult your service provider or your printer documentation for the recommended image resolutions.

85 lpi: Average screen typically used to print newspapersC.
133 lpi: High-quality screen typically used to impress four-color magazinesD.
177 lpi: Very fine screen typically used for annual reports and images in art books
Resolution specs for printing images
A resolution of 300 pixels/inch is the manufacture standard for loftier-quality prints. This resolution volition ensure that your image looks sharp and detailed when printed.
A resolution of 300 pixels/inch is perfect for viewing small prints from up close, but you can also opt for lower resolutions for big prints if they are intended to be viewed from far away. For case, if you are printing a billboard to be erected off a highway, you lot can print it at a lower resolution without compromising on the quality, considering high resolution becomes less important as you lot move further from the prototype.
Default resolution in printers
Usually, printers have their default impress resolution at 300 pixels/inch, and if yous print an epitome with a lower resolution, they will accommodate their image settings to print your prototype at the default resolution.
This ways, you cannot print an epitome at less than the printer’south default resolution, and if you don’t enlarge the prototype, your printer volition.
View the impress size onscreen
You can do either of the following to view the print size onscreen – either go to
. Or, select the
in the options bar.
The prototype is redisplayed in its gauge printed size, as specified in the
area of theImage Size dialog box. The size and resolution of your monitor affect the onscreen print size.
is changing the amount of image data as you alter either the pixel dimensions or the resolution of an image.
is decreasing the number of pixels – when you downsample, information is deleted from the epitome.
Upsampling is increasing the number of pixels – when you upsample, new pixels are added.
You specify an interpolation method to determine how pixels are added or deleted.
Resampled up (selected pixels displayed for each set of images)
Go on in listen that resampling can result in poorer prototype quality. For example, when you lot resample an image to larger pixel dimensions, the epitome loses some detail and sharpness. Applying the
Unsharp Mask filter
to a resampled image can help refocus the prototype details.
Yous can avoid the need for resampling by scanning or creating the image at a sufficiently loftier resolution. If you want to preview the effects of changing pixel dimensions onscreen or to print proofs at unlike resolutions, resample a indistinguishable of your file.
Photoshop resamples images using an interpolation method to assign color values to any new pixels based on the color values of existing pixels. You can choose your method in the
A fast simply less precise method that replicates the pixels in an image. This method is for use with illustrations containing edges that are not anti-aliased, to preserve hard edges and produce a smaller file. However, this method can produce jagged effects, which become credible when you distort or scale an image or perform multiple manipulations on a selection.
A method that adds pixels by averaging the color values of surrounding pixels. Information technology produces medium-quality results.
A slower just more than precise method based on an test of the values of surrounding pixels. Using more complex calculations, Bicubic produces smoother tonal gradations than Nearest Neighbour or Bilinear.
A good method for enlarging images based on Bicubic interpolation but designed to produce smoother results.
A adept method for reducing the size of an image based on Bicubic interpolation with enhanced sharpening. This method maintains the item in a resampled epitome. If Bicubic Sharper oversharpens some areas of an image, endeavor using Bicubic.
Yous can specify a default interpolation method to apply whenever Photoshop resamples image data. Choose Edit > Preferences > General (Windows) or Photoshop > Preferences > General (MacOS), and so choose a method from the Image Interpolation Methods menu.
Change pixel dimensions of an image
Changing an image’s pixel dimensions affects not only its onscreen size but as well its image quality and its printed characteristics—either its printed dimensions or its epitome resolution.
To maintain the current ratio of pixel width to pixel height, select
Constrain Proportions. This option automatically updates the width as you change the height.
Pixel Dimensions, enter values for
Height. To enter values as percentages of the current dimensions, choose
every bit the unit of measurement. The new file size for the image appears at the top of the
dialog box, with the onetime file size in parentheses.
Make sure that
is selected, and choose an interpolation method.
If your prototype has layers with styles practical to them, select

When you lot cease setting options, clickOK.
For best results when you produce a smaller prototype, downsample and apply the Unsharp Mask filter. To produce a larger image, rescan the prototype at a higher resolution.
Change the print dimensions and resolution
When creating an image for print media, it’s useful to specify paradigm size in terms of the printed dimensions and the image resolution. These two measurements – referred to as the
document size – determine the total pixel count and therefore the file size of the epitome.
Document size also determines the base size at which an epitome is placed into another application. Yous can further manipulate the calibration of the printed image using the Print command; even so, changes you brand using the Impress command touch on only the printed epitome, not the document size of the epitome file.
If you turn on resampling for the epitome, you can alter print dimensions and resolution independently (and change the total number of pixels in the image).If you turn off resampling, you can change either the dimensions or the resolution—Photoshop adjusts the other value automatically to preserve the total pixel count.
For the highest print quality, it’s recommended to change the dimensions and resolution get-go, without resampling. And so resample only as necessary.
Modify the impress dimensions, image resolution, or both:
To change only the print dimensions or only the resolution and adjust the full number of pixels in the image proportionately, select
and and so choose an interpolation method.
To modify the print dimensions and resolution without changing the total number of pixels in the prototype, deselect
To maintain the current ratio of epitome width to image height, select
Constrain Proportions. This choice automatically changes the width equally yous change the height.

option uses the width and gutter sizes specified in the
Units & Rulers
Resolution, enter a new value. If desired, choose a new unit.
To restore the initial values displayed in the
dialog box, hold downwards Alt (Windows) or Option (MacOS), and click Reset.
What affects file size?
File size depends on the pixel dimensions of an image and the number of layers it contains. Images with more pixels may produce more than detail when printed, merely they require more disk infinite to store and may take more than fourth dimension to edit and print.
Make sure your files are not too large – for large files, reduce the number of layers in the prototype or modify the image size.
You tin view the file size data for an image at the bottom of the application window.
