Enlarging any file to a classroom poster - for free!

steps to make a poster for free

If you aren't given the option to print your PDF files as large, multi-page posters in the PDFs "print" screen, this post is for you!

That up there is the end result of figuring it all out all these years later. Pretty impressive, right? Yeah not really! BUT, it took me a while AND saves me an expensive trip to Staples (who wanted $42!!) or waiting for something to come in the mail (those are shinier but not very highlighter-friendly). Tomorrow I will tape my new homemade poster together at school so that I can highlight it as my students highlight their own smaller versions for their notebooks. As you may have guessed, we are starting quadratic word problems tomorrow.

The steps:
1: Go to ZamZar.com to convert from doc (or pdf or png...) to jpeg
2: Upload your new jpeg to BlockPosters.com
3: Choose your size and save as pdf to your computer (see photos)
4: Print from saved file (*choose "fit" in the print settings)
5: Cut, tape, hang in classroom!

(*in the photo above I didn't remember to click "fit", which is why the words are a little cut off. I used a marker to fill in the missing parts after taping together, but choosing "fit" in the pdf print settings avoids this extra step.)

Photo directions:
Because BlockPosters only accepts jpegs, you'll:

1) Upload your pdf into ZamZar:

2) Choose to convert to jpeg, and enter your email address. 

Soon you will get an email that allows you to download and save the jpeg.

Once you have your jpeg, it's time to head over to BlockPosters. 

You can choose how big you want your poster. For my poster I chose "2 Pages Wide". In the photo above, I showed what "3 Pages Wide" looks like in the settings. 

Click "Create My Poster" and you're good to go! BlockPosters does add a few pages into the file, so I save the file to my desktop and choose to print only the pages I want. 

I have used these steps to make a few posters that accompany our word walls. It's pretty cool seeing the posters come together and I find it fun taping the pages and seeing the final product. I'd love to see your posters by tagging me on social media!


  1. Do you use these site to print your "word wall" bundles? I have purchased your bundles. Just wondering if your print them the way they are or enlarge them. Thanks in advance.

    1. Thank you for asking. I make the word walls to be printable as-is. They will cover roughly 30 square feet (give or take depending on the grade level) without any enlarging.
