What Are Slimline Cards?

The newest card making craze is sweeping the crafting community, and it's known as slimline cards.  Slimline describes the look of these cards - they are tall and slender vertically or long and skinny horizontally. Think of it this way - if A2-sized cards are wine glasses, slimline cards are champagne flutes. So let's have a toast & celebrate this fun & fabulous new style!

What Size Are Slimline Cards?

The standard size of slimline cards is typically 3.5" x 8.5" (or 8.89 x 21.59 in centimeters). This size can vary slightly from card to card but is generally meant to fit within a #10 standard envelope, which measures 4.125" x 9.5".

What Envelopes Do You Need For Slimline Cards?

Do you know that box of standard #10 business envelopes in your closet can be used for slimline cards? It's true. Your tall, skinny, beautiful slimline card slides sideways into a standard-sized business envelope, and it's ready to go out to make someone's day.

What About Postage?

We have great news! That slimline envelope, also known as a #10, only requires standard postage. So assuming you haven't used any heavy or dimensional embellishments to make your slimline card bulky, it only needs the standard stamp to get delivered to your recipient.

How Do You Make a Slimline Card Base?

Making a card base for slimline cards is super easy. All you need is a trimmer and a scoring tool. You can start with a piece of 12" x 12" cardstock or a piece of 8.5" x 11" - which makes these a very versatile card making option. Cut your piece of cardstock down to 7" x 8.5. Along the 7" side, score and fold in the middle at the 3.5" mark. This will leave you with your skinny slimline card base for tall cards or long cards in slimline size.
