A free tool from our Akron, Ohio print studio
Upload your artwork to find its aspect ratio and a comfortable print size at 300 PPI. Then plan the right frame, border or custom size.
Fine art printing for artists, photographers, and the images you love.
See your exact aspect ratio and how large your file can print at 300 PPI, together.
Your artwork stays in your browser. No account needed. When you order, you’ll upload the file on our print shop.
Your artwork · width : height
Calculated from pixels ÷ 300, without enlarging the file. This checks resolution, not sharpness or color. Existing borders count toward the file size; use a tightly cropped scan or image of the artwork.
Common sizes at 300 PPI or higher · no cropping
Make framing easier
Prepare this shape in White Border Builder ↗In the builder, upload your artwork and choose “Fit a frame with an even border.” Enter one of these frame sizes and set the border to zero for an edge-to-edge print, then adjust the crop preview before downloading. To keep the whole picture instead, choose “Fit into a common frame size” and add white space.
Enter one side to keep the artwork’s shape, or both sides to check a frame size. All dimensions are width × height.

Planning a new artwork file? Enter your print size to see how many pixels you need. You can also convert pixels back to inches—no upload needed.
PPI means pixels per inch. Start with 300 for detailed print planning. Leave height blank to convert just one measurement.
This calculates dimensions; it does not resize your file or add image detail. Pixel requirements round up to whole pixels. Inch results show up to four decimal places.
No file handy? Enter dimensions manually to check frame sizes or resize proportionally.
Measure the artwork itself and enter the width and height in inches.
Use the size of the artwork itself, not the outside frame size.

Common sizes in this ratio
Enter your current size, then add one new width or one new height. This calculates dimensions; it does not resize or edit your file.
To keep the same proportions, use just one of the new size fields.

Aspect ratio simply means the shape of your picture. It helps us find print sizes that keep the whole image. If a frame is a different shape, you can trim the picture’s edges or add a border to keep everything visible.
300 pixels per inch is a useful target for detailed prints. We divide your actual pixel dimensions by 300; a file’s saved DPI label does not change this calculation. Blur, compression and artificially enlarged pixels can still affect the result. If you’re unsure, ask the studio before ordering.
Possibly. A larger print has fewer pixels per inch, so the artwork, viewing distance and material matter. Check your desired size above, then contact us if you’d like help deciding. Enlarging a file does not restore missing detail.
Measure the opening that will show the artwork. Use the White Border Builder to keep the full image with border space, or the Custom Size Request tool to plan a print outside the standard options. For a mat, check the visible opening as well as the frame size.
JPG, PNG and WebP files work here, including supported phone photos. For PDF, TIFF or HEIC, export a full-resolution JPG or PNG first. A snapshot of a painting measures the whole photo, including the wall or frame; use a tightly cropped, straight-on image for a useful estimate.
