Start making your own homemade DIY poster using your own images today! Using a method called "tiled printing", you can print images larger than a standard sheet of paper. This tiled printing program overlays a grid on your image. Each cell (or tile) is then printed on a single piece of paper. You can then arrange the tiles to recreate the enlarged image.

Why do my printed images not match what I see in my browser?

To make sure the printed image matches what you see in your browser, make sure the "Scale" option on your browser is set to "Fit to page"

What is the best way to assemble your poster together?

Below are two common approaches.
A. Assemble the poster face-down using masking tape to stick the printed pages together. This allows you to move and reposition the poster in one operation.
B. Use two-sided tape. Individual stick each piece of paper on the wall.

How can I remove the excess borders?

Most printers cannot print on the entire piece of paper. Hence you will most likely find margins around the outside. You can use a a scissors or a paper cutters to remove the extra borders around the outside. Note: Some people leave the margins on the paper to give their poster a "tiled" look.

Why is my poster pixelated?

For better quality, either try reducing the size of your poster or uploading an image with higher resolution.

How can I maximize the printing on each piece of paper?

The easiest approach is to select the "AutoFit" option. To completely minimize wasted paper, select the number of sheets "wide" and the number of sheets "high" that most closely match your paper size. The default settings assume you are printing on Letter paper (8.5in x 11in) [21.6cm x 28cm]. If you want to maximize every single inch of paper, then the dimensions of the image divided by the number of sheets needs to equal "one" as shown in the formula below.
For example, if your image is 2448 pixels wide and 1584 pixels in height, then one perfect ratio is by setting sheets "Wide" to "4" and "High" to "2".

How long does uploading or downloading take?

Depending upon your network connection, it may take several seconds or minutes or more to upload your image or download the completed PDF file.

What happens to the uploaded images.

The images that are both uploaded and the created (pdf files) are stored in a temporary location. A cleanup operation deletes all files approximately every 10 minutes. See resizing and printing images for more help on resizing images consistently, or printing images (on multiple pages).
