Peripheral Power: How To Use Your Scanner To Enlarge Images
This is one of those posts where you have to admit to being a dope so you can pass along a tip that might help others.![]()
Gotta grit my teeth… OK, here goes!![]()
Many years ago I spent considerable time and effort thinking up humorous greeting card designs and submitting them to American Greetings and other card companies.![]()
At some point I thought: instead of submitting just one idea per page, I could save postage by squeezing three designs onto a page.![]()
So that’s what I did. I put the front of each card on the left, and the inside greeting on the right. I used plain white copy paper, 8.5″ x 11″, so each B&W sketch was about 3″ high.![]()
Here’s what a typical page looked like:

I didn’t have much luck, but I saved all the sketches hoping I might be able to use them someday.![]()
Fast forward to the present, where every artist and his sister seems to have an online store, myself included.![]()
Every so often I’d come across my old card ideas and think: These are great!! (I’m a big fan of my own work.)![]()
Then I’d think: I should scan these in and color ’em and upload them to my online store where they’ll all be big sellers!! (My electrician tells me to think positive.)![]()
Then I’d smack my forehead and think: Ya dope! Why’d ya draw ’em so small?? They’re only 3″ high, and the average greeting card is 5″ x 7″.![]()
Now you might be thinking: Couldn’t you scan them in
and then use an image-editing program like Photoshop or Pixelmator to enlarge them? Yes, I could– but doing so would thicken all the lines and give the drawings a very dense look.![]()
So the forehead-smacking went on for years, until one night, several weeks ago, I’m lying in bed and I thought: what if I scanned them in at a much higher resolution?– say 600 or 1200 dpi, instead of the usual 300 dpi?– would that possibly enlarge them at the same time?![]()
So next morning I’m anxious to give it a try. Before I do, however, I decide to do a quick search. I bring up Google and type: “Can you enlarge an image with a scanner?”![]()
My top search result was a Q&A forum entry from 2006 (!!). The page title was: Scanning hard copy old photos HOW TO GET THEM LARGER.![]()
The question: “I have some very small old photos– how can I get them to scan larger?”![]()
Here’s the first part of the answer:![]()
I use Epson’s line of scanners… I have the option of performing the scan in ‘professional mode’ as opposed to the fully-automatic process, and there exists an option to define a custom target size… (my emphasis)![]()
I sat there blinking. I have an Epson scanner myself that I bought back in 2015. You don’t suppose…![]()
I launched the scanner app, and tucked away in the Settings window I see a section I’d never noticed before: Target Size.![]()
=> head-slap, head-slap, head-slap!! x 100![]()
To cut a long and embarrassing story short: I set Scale = 250% and scanned the above page at 300 dpi.![]()
Instead of getting an 8.5″ x 11″ image (2550 x 3509 pixels), I got a 21.25″ x 29.25″ image (6375 x 8774 pixels).![]()
Instead of 3″ high, my little B&W sketches were now about 7.5″ high– and looked perfect.![]()
So that’s my tip: if you use a scanner for line drawings, photos, or any other hard-copy image, check your scanner settings. If you’ve got a Target Size option, you can enlarge your images as you scan them.![]()
OK, maybe you don’t have a scanner– but chances are you have some kind of device plugged into your computer. Ask Google a few questions about it. You might discover it can do some tricks you didn’t know about.![]()
Here’s how those three Christmas card designs turned out after I finished them in Pixelmator. You can find them all in my online store, including several possible inside greetings for each card.
