Our guide to image resolution includes:

• What is epitome resolution?

Whether you're printing marketing tools such every bit business cards, brochures, and postcards or keepsakes such as family photos, refrigerator magnets, or greeting cards, y'all tin print picture-perfect artwork with these tips for proper image resolution.

What is epitome resolution?

Epitome resolution tin be defined every bit the level of detail in an image. Raster images are comprised of a series of pixels, where resolution is the]]> total number of pixels forth an prototype's width and pinnacle]]>, expressed as pixels per inch (PPI).

The greater the PPI, the greater the particular and the better the impress quality – whether you're printing invitation cards for an upcoming event or a family unit photo to frame on your wall.

Ofttimes, PPI and dots per inch (DPI) are used interchangeably; nevertheless, PPI and DPI are non identical. Though they are like, PPI refers to the pixels per inch on your computer screen, while DPI refers to the ink dots per inch applied by a press press.

If your press visitor requires artwork in a certain DPI, chances are they're really referring to PPI. Again, the easiest way to think about it is:

• Pixels per inch (PPI) refers to image resolution on your calculator screen
• Dots per inch (DPI) refers to image resolution on printed paper

Note: Resolution applies to raster images, which are comprised of pixels, just not vector images, which employ mathematical calculations to produce images. Learn more about the difference betwixt raster and vector images.

What is the all-time resolution for printing?

What resolution should photos be for press? What should DPI (or PPI) exist for press high-quality artwork? In many cases, the all-time resolution for printing is 300 PPI.

At 300 pixels per inch (which roughly translates to 300 DPI, or dots per inch, on a printing press), an prototype will appear sharp and well-baked. These are considered to be high resolution, or loftier-res, images. (If you're working with photography, y'all're probably working with high-resolution JPEGs, which tin be printed every bit stand-solitary photos or incorporated into your brochure printing and other projects).

What about the all-time resolution for pictures online? Web images are commonly created in 72 or 96 PPI, which are considered to exist low resolutions. They're perfect for the spider web considering they feature smaller file sizes that can load quickly online, only they exercise not translate well to print.

Low resolution, or low-res, images will announced pixelated and blurred after press – even though they might look perfect on your computer screen. That's because in that location aren't enough pixels per inch to maintain a sharp epitome at large document dimensions.

• Document dimension: The physical size of the printed piece. Example: four" x half-dozen" postcard
• Resolution: Pixels per inch (PPI)

Information technology'southward important to understand the relationship between document dimension and resolution.

For instance, a iv" x 6" epitome at 72 pixels per inch would have a total pixel dimension of 288px (superlative) by 432px (width). That means there would but exist 288 pixels spread out over four inches. To brand that stretch, each of those 288 pixels would need to be rather large, resulting in a blurry, pixelated image.

A iv" x 6" image at 300 pixels per inch (a common size for postcard printing), on the other mitt, would have a total pixel dimension of 1,200px (elevation) by 1,800px (width). Compared to the 72 PPI version, the four-inch bridge would exist represented by 1,200 pixels instead of 288 pixels – or 912 more pixels. That means the pixels can exist smaller, resulting in higher definition and articulate, sharp image.

The best resolution for a given project depends on multiple factors, including the blazon of project you're printing and the type of printer you're using. For example, if you want to impress high-quality business flyers on an get-go or digital printing press, your flyers should exist 300 PPI. If you want to print 8" x ten" photos on your inkjet printer, a resolution of 220 PPI might be enough to produce adequate results.

Project	Printer	Resolution
Marketing tools (brochures, business cards, flyers, posters, etc.)	Offset or digital printing press	300 PPI
Photos (4 x vi, five x 7, 8 x ten)	Kickoff or digital printing press	300 PPI
Photos (iv ten 6, 5 x vii, viii x 10)	Desktop inkjet printer	220 PPI
Print on need garments and accessories (T-shirts, mugs, hats, etc.)	Large format inkjet printer	150 to 300 PPI
Screen printed garments (hats, shirts, etc.)	Screen printer	150 to 300 PPI

Those are examples; every printing company has its own resolution requirements. The best pixel size for impress can vary between printing companies, press formats and printing presses. Information technology's best to bank check with your printing company earlier y'all create your artwork then you lot tin can format it in the proper resolution.

The size of your final printed projection tin can determine whether you can impress in a lower resolution; for case, a 150 PPI image might await fine at 4" x six" just look blurry at 8" ten 12". Often, information technology'south best to err on the side of caution and create your artwork in 300 PPI, since you tin downsize if needed without sacrificing quality.

You might wonder how resolution relates to cameras, specially if yous're taking pictures with an iPhone or other smartphone. The higher the resolution of your camera, the larger you can impress images and still get a clear output.

How many pixels are in 300 PPI depends on the document dimensions. Allow's say, for example, y'all want to impress an eight" ten 10" photo at 300 PPI (the best resolution for a photo, in most cases).

You can multiply both 8 and 10 by 300 to get the full pixel dimensions of the finished image.

• 8(300) X 10(300) = 2,400px X iii,000px

You tin can multiply both 8 and 10 by 300 to become the full pixel dimensions of the finished image.

• 2,400 X three,000 = vii.two million pixels

Another name for vii.2 meg pixels is 7.two megapixels (MP); which ways yous'll need a minimum 7.2 MP photographic camera to get the best resolution for your viii" x 10" photo.

Fortunately, the latest-model iPhones characteristic camera resolutions upward to 12 MP; and DSLR cameras often feature eighteen MP and upwards, so you don't need to be a professional photographer to start with a high-resolution epitome.

You tin utilise this knowledge to effigy out other questions, such as "how large is 1920 x 1080 in inches?" All you need to know how to convert pixels to inches.

If you know the PPI – again, let's say 300 – you divide the full dimensional pixels to decide the inches:

• 1920/300 = half-dozen.four
• 1080/300 = 3.6

So, a 1920x1080 image in 300 PPI would be 6.4" ten three.6"

For another instance, nosotros might want to effigy out how many pixels are in a 5 x 7 image. Again, nosotros need to know the PPI.

If information technology's 300 PPI, you lot would multiply that figure past 5 and seven, respectively:

• five(300) = one,500
• 7(300) = two,100

So a 5 10 7 image at 300 PPI would be 1,500px by two,100px.

Now, you can effigy out the total megapixels by multiplying width times pinnacle:

• 1,500(two,100) = 3.fifteen meg pixels, or 3.xv megapixels

In this case, you tin can print a high-quality 5 x vii photo past snapping a picture with a 3.ii MP (or greater) camera.

That'southward pretty small, but if you're designing a brochure it might exist big enough, dimensionally, for an prototype set in the text.

ii.How to increase image resolution in Photoshop (and maintain prototype size)

If you want to increment image resolution yet maintain document dimensions, you would follow the same process as above – except this time, you'll make sure the "resample" box is checked:

• Click Image > Image Size
• Bank check the "Resample" box
• Set the resolution to 300 PPI and click "OK"

In this case, Photoshop will attempt to add together new pixels between existing pixels to increase the resolution and maintain dimensional size.

• Replicates image pixels merely is less precise than other methods.
• Bilinear
• Adds pixels co-ordinate to the average color values of surrounding pixels.southward

You lot can play around with each of these options to see which produces the all-time results for your image. However, resampling ofttimes leads to undesirable effects such as poor image quality. Many experts recommend resampling by only v to 10 percent to minimize image distortion.

Yous can try to regain lost detail with Photoshop'southward Unsharp Mask filter, though results might be mixed.
