Our Order Wizard will place your uploaded file on white canvas representing your chosen print size. If your original file size is not in proportion, you may want to crop it, or adjust the final output size to the right proportion. A good rule of thumb is to take your desired width and length and divide them by the same # to get the proportionate size.Įxample: if your desired output size is 24 x 36, divide both sides by 4 to get an original file size of 6 x 9. If the dimensions of your file are not the exact size of the final output, make sure your original file is in the same proportion as the desired output size.įor example, a 4 x 6 original file sizes up to 16 x 24, not 18 x 24, and an 8.5 x 11 sizes up to 24 x 32, not 24 x 36. Use the table below to find the recommended size of your original file at 300 dpi for the common poster sizes below. High Quality output is necessary only for ultra-photographic quality detail or art reproduction and for designs with small text. Normal Quality output is suitable for the majority of poster applications, including displays, banners, general posters, photo enlargements, signs, etc. Use this guideline for designs with text such as presentations and signs.
(This means a 24 x 36 poster your original file should have 300 dpi at 12 x 18).
Designs with text such as presentations and signs need a minimum of 150 dpi at actual size up to 300 dpi at actual size.įor the highest quality output, your original file should have 300 dpi resolution at 50% of the final size. (this means for a 24 x 36 poster, your original file should be at 300 dpi and 6 x 9). Try to have an original source file that is proportionally 25% to 50% of your desired final output size at a high resolution.įor normal quality output, your original file should have 300 dpi resolution at 25% of the final output size. You can use our handy File Quality Check tool to check your file’s resolution and get our suggestion on the maximum size you can print it as a poster.
