What resolution does your artwork
actually need?

The short answer is to keep one strong master file and make purpose built copies from it. Websites care about pixel dimensions and file weight. Open calls care about whatever limits their portal sets. Prints care about pixels at a physical size. Reproduction and archives care about all of that, plus color, scale, crop, and the quality of the original capture.

This guide explains how those jobs differ, how to calculate a useful print size, and what to ask for after a documentation session. Resolution gets much simpler once it stops pretending every file has the same future.

Start with the final use

Resolution is a relationship between the pixels in a file and the size at which those pixels need to appear. That is why asking for a high resolution image without naming the use produces vague answers. High compared with what?

A gallery website, an open call, a catalog, a large editioned print, and a long term archive all put different pressure on the file. The same master capture can often support several of them, but each destination needs its own export. Sending the master everywhere creates slow downloads and awkward submission failures. Sending the web copy everywhere eventually creates the opposite problem, a file that looked fine online and becomes visibly soft the moment somebody asks for a printed page.

Begin with the largest realistic use. If the artwork may be reproduced at 20 inches wide, say that before capture. If the image only needs to live on a portfolio site and in open calls, say that too. Planning for a real destination is more useful than ordering the biggest file available because bigger sounds responsible.

Check pixels before ppi

The first useful numbers are the pixel dimensions. A file that measures 6000 by 4000 pixels contains the same number of pixels whether its metadata says 72 ppi, 240 ppi, or 300 ppi. Changing that ppi label without resampling does not add detail. It changes the proposed relationship between those pixels and a physical print size.

On a screen, the browser mainly cares about the actual pixel dimensions. It does not quietly improve an image because the file says 300 ppi. In print, the pixel count gets divided across inches. A 6000 pixel wide file can print 20 inches wide at 300 pixels per inch, or 30 inches wide at 200 pixels per inch. The first version packs the same information more tightly.

Ppi and dpi also describe different things. Ppi describes image pixels per printed inch. Dpi describes the printer's physical dots. They often get used interchangeably in conversation, which is survivable as long as the actual request includes pixel dimensions and print size. The file does not become more detailed because everyone says dpi with confidence.

Resolution for websites and open calls

A web file should be large enough for the way the site displays it and light enough to load without making the portfolio feel heavy. For many artist sites, a JPEG around 2000 to 3000 pixels on the long edge gives a useful balance for full width display and moderate zoom. The right number still depends on the site, the crop, and whether visitors can open a larger view.

The ppi label is not the deciding factor online. Pixel dimensions, compression, color space, and file size are. An sRGB JPEG is the practical default for most web uses because browsers and common platforms expect it. Keep the master somewhere else. A website export should be a delivery copy, not the last surviving version of the artwork.

Open calls are stricter because the portal may set a maximum file size, exact dimensions, or a required format. Follow those instructions even when they produce a smaller file than your website uses. A 5 megabyte limit is not asking whether your camera is good. It is asking whether the upload system will accept the result. Export a separate copy and keep the master untouched.

This is also where file naming matters. The sharpest image in the folder is less useful when the title, year, and view are impossible to identify. Resolution helps the reviewer see the work. A clean name helps them understand which work they are seeing.

Calculate resolution for print

For a close viewed print, 300 pixels per inch is a strong default. Adobe also uses 300 ppi as its general high quality print recommendation, while noting that printer requirements and viewing distance can change the answer. The printer's own specification wins when one is available. You can read Adobe's current explanation of pixel dimensions and printed image resolution if you want the technical version without the small cloud of folklore that usually follows this topic around.

The calculation is simple. Multiply the desired print width and height in inches by the target ppi. An 8 by 10 inch print at 300 ppi needs 2400 by 3000 pixels. An 11 by 14 inch print needs 3300 by 4200 pixels. A 16 by 20 inch print needs 4800 by 6000 pixels.

Large prints are often viewed from farther away, so they may work well below 300 ppi. That is a production decision, not permission to guess. Ask the printer what it wants for the process, paper, and viewing distance. A 24 by 36 inch exhibition print at 300 ppi would need 7200 by 10800 pixels. If the printer says 200 ppi is appropriate, the requirement drops to 4800 by 7200 pixels. The physical use decides whether that difference is visible.

Allow room for cropping too. If the final print shape is narrower than the artwork's original proportions, part of the captured frame will be removed. Calculate from the cropped pixel dimensions, not the untouched file that looked larger in the folder.

Plan differently for reproduction

Reproducing an artwork is more demanding than making a reference print. The file may become an edition, a catalog image, or a printed object that viewers compare closely with the original. Resolution matters, and it shares the job with color accuracy, even lighting, geometry, focus, and faithful editing.

Start with the reproduction size and process. A small book image and a full size print need different amounts of detail. A flat matte work may capture cleanly in one frame. A large or highly detailed piece may benefit from a higher resolution camera, a scanning workflow, or several carefully aligned captures that are stitched together. The correct method follows the work and the final size.

Ask the printer or publisher for pixel dimensions, color space, file format, bleed, and any sharpening guidance before the final export. Do not repeatedly resize the same JPEG as new requests arrive. Make each delivery from the master so compression and resampling do not accumulate like a very boring family curse.

A larger file cannot repair a weak capture

Resolution describes how much information the file can hold. It does not guarantee that the information is accurate. A large image can still be softly focused, unevenly lit, clipped in the highlights, distorted by camera position, or shifted in color. More pixels simply describe those problems with unusual commitment.

Artwork documentation needs a clean capture before it needs a large export. The camera should be square to flat work. Lighting should reveal the material without adding accidental glare or false texture. A neutral target can anchor color and exposure. Focus should be checked on the actual surface, not only on a small camera preview.

For cultural heritage imaging, the Federal Agencies Digital Guidelines Initiative treats resolution as one measured part of a larger quality system that also includes targets, metadata, scale, and imaging performance. Its technical guidelines for still image digitization are more rigorous than most working artists need, but the principle travels well. The number in the file header is useful only when the capture behind it is trustworthy.

Keep a master and make derivatives

A practical file set begins with one full resolution master. That master keeps the best available pixel dimensions, the complete crop, and the strongest color information the workflow produced. It may be a TIFF or another high quality working format. The exact choice depends on how the file was captured, edited, delivered, and archived.

From that master, create smaller derivatives for specific jobs. A web JPEG can be resized and compressed for fast display. An open call file can match the portal's exact limits. A print file can be prepared at the requested dimensions and color space. None of those copies should replace the master.

This structure also keeps future decisions open. A larger master may support a catalog page that nobody planned during the original shoot. A web copy cannot grow back into that master later. Storage is inexpensive compared with documenting the work again after it has sold, shipped, changed, or entered a collection.

Keep the versions easy to recognize. A simple structure such as Master, Web, Print, and Submissions is enough. Add the artwork title or inventory number to every filename. The system should still make sense when you open it six months later and remember none of the heroic clarity you felt while exporting it.

How to check an existing file

Open the file information panel in your image editor or operating system and find the pixel dimensions. Ignore the ppi label for a moment. Write down the width and height in pixels, then compare them with the intended use.

For print, divide each pixel dimension by the target ppi. A 4500 by 3000 pixel image becomes 15 by 10 inches at 300 ppi. If the file needs to print larger, ask the printer whether a lower effective ppi is acceptable at the intended viewing distance. If the answer is no, return to a better source file or recapture the work.

Then inspect the image at 100 percent. Check important edges, brushwork, paper texture, signatures, and any small marks that need to survive. Look for motion blur, missed focus, glare, clipped highlights, and color noise in dark areas. The calculation tells you how many pixels exist. The inspection tells you whether those pixels carry useful detail.

Finally, confirm the crop and orientation. A file can have generous dimensions and still fail the job because the artwork edge is missing, the frame was included when the art needed its own record, or the aspect ratio leaves no room for the requested print. Resolution never gets to work alone.

What to request at delivery

Ask for files by job rather than using the phrase high resolution as the entire brief. Name the largest intended print or reproduction size. Share any open call specifications. Say whether the work needs a web portfolio image, archive record, press file, detail view, or full size reproduction.

A useful delivery usually includes the full resolution master, a web ready JPEG, and any specific submission or print files already known. Confirm the pixel dimensions of the master. Ask whether the web version is in sRGB. Keep the file names tied to the artwork record, and keep the original master separate from every resized copy.

The goal is not to collect the largest possible folder. It is to leave the documentation session with files that already know what they are for. Resolution becomes straightforward once each version has one job. The master protects the future. The derivatives make the work usable today.
