Enlarge A Photo Without Losing Quality
One of the biggest challenges you’ll face when you want to resize an image for tracing is how to make a photo bigger without losing the crisp quality. There’s nothing worse than taking the time to enlarge a traceable only to find that the lines are blurry and hard to see.
No worries, though! To keep your photo looking its best, you’ll want to understand pixels, resolution, and the difference between dpi and PPI.
Pixels are tiny little squares that make up any image displayed on a computer screen. Letters, numbers, symbols, pictures, everything is made up of pixels. The more pixels you have to play with, the better chance you have of keeping the clarity of your image.
Resolution is the size of each pixel. The smaller the pixel, the better the resolution becomes.
DPI (dots per inch) refers to the amount of ink or toner printed on a piece of paper per inch, whereas PPI (pixels per inch) refers to how many pixels are in an inch of a computer or other digital screen.
When you enlarge a photo for tracing, you want to have plenty of pixels so you can size up, and you want a higher amount of pixels per inch.
Okay, this will be a weird analogy, but let’s say you have two cans of sardines. In one can, there are 6 sardines, and in the other can, there are 10.
When you look at the cans side-by-side, the can with more sardines looks neater because there is less space between each fish, and it’s hard to see where one sardine begins and the other ends.
The same is true for pixels per inch. The more pixels you can smush inside an inch, the crisper everything will look. The hard edges of each square pixel become less distinguishable from its neighbor. I hope that makes sense.
- If downloading from Pixabay or another website that has free images go for the highest resolution in the download window
- Photos taken with a phone that has a 10 megapixel camera will work great
- Artifact Uprising has an excellent graphic showing how much you can enlarge an image depending on the pixel dimensions of the original photo

Knowing that each page is 8.5 x 11″ and there will be a margin around each page, figure out how many pieces of regular sized printer paper you’d need to cover your canvas. For example, my canvas is 16 x 20, so I know that I need my image to cover at least 2 + pieces of paper, both in width and height.
- Go into the Set Custom Page Breaks dialog and start clicking and dragging the little blue dots located on the right side of the image and the bottom
- Remember that there will still be a bit of a margin around each piece of paper to enlarge your photo so take that into consideration.

- If image is larger than the area shown on spreadsheet, you have to click on a cell and then use up and down arrows
How To Assemble Enlarged Traceables
Now that you’ve got all of your pages printed off, how do you put them together? It’s fairly simple, but I’m going to share with you my process so you can get your resized image together in a jiffy.
- Have a copy of your photo nearby so you can use it as a reference to put your pages in the correct order
- Leave one side intact, both horizontally (top or bottom) and vertically (left or right), so you can either tape or glue your sheets of paper together easily
- Start by joining the top row of pages together using glue or tape (I prefer tape, so I don’t have to wait for the glue to dry)
- Continue joining each row of pages together until you’ve got them all together
- Attach the second row to the bottom of the first row
- Continue until all rows are attached, giving you one large image
- Add additional pieces of small tape to secure the papers to each other
- Flip the photo over and add more tape where needed
- Using scissors, cut off any remaining margins along the outside edge of the enlarged image
- Extra Tip: If you’re using tape to secure your pages together, make sure it’s transparent tape so you can easily see each shape and line when you’re ready to trace
