If photos represent precious memories, why downsize them all the time? Why not make them as big as life for a change? Instead of shrinking and binding your best moments to a small frame, surround yourself with your most cherished images and create a life-size poster with the help of these easy tips.


The camera you use should be able to produce high-resolution images. These days, most cameras can do it, but you have to select the right settings or you will end up with small and unusable JPEG files. If you are not sure how to change output file, read your camera’s manual before shooting.

In addition, your photo should be correctly exposed and sharp. If you are using an older shot, choose one that meets these needs.

If you are taking the photo just for the poster, create adequate lighting conditions and use a stable surface or a tripod to support your camera to avoid camera shake. Keep the ISO speed low to minimize noise — use the camera’s native ISO if possible.

Photos straight from the camera rarely turn out perfect, so some basic editing may be necessary to fix any problems. If you want the photo to look as close to the original as possible, just adjust contrast, brightness, saturation, and crop slightly to get rid of clutter and distracting elements. You may also want to apply very light sharpening to the image.

To make the poster at home, you have to split your original photo into multiple pages and then print them all. You can do this with most image editors, but you will have to crop manually, either using the marquee tool or the slice tool and print each section separately.

To make things easier, there are also applications like ProPoster, The Rasterbator, Block Posters and Posterazor that can help you achieve the result you want. Test your print settings to ensure the printed image is crisp and the colors are accurate.

After you are finished printing, you will need to assemble the poster. Trim the blank borders from the sheets of paper and tape them all together. If you need support, you can mount all the parts onto foam board — they are pretty cheap and available from most office suppliers.

If the previous steps seem like a lot of hard work, you can let a commercial printing service handle everything for you. Note that some printing labs may apply sharpening and other adjustments to your file without specifying it, so ask them in advance to avoid any unpleasant surprises. Also, contact them to learn their color profiles and resolution requirements.

  1. Kevin, do any of the printers that you guys reviewed do posters this size? Thanks.

      Great questions, regular_dude. I believe many of them do offer specialty orders to account for unique requests such as an extra large poster. Contacting the printer would be best to insure you are both on the same page about what they can and cannot do.
