Cardmaking Basics: Sizing, Scoring, and Your First Card

A handmade card is one of the most satisfying small projects there is: an hour’s work, a short list of materials, and something a person keeps. The craft rewards a little planning at the start, though, mostly around sizes. Get the base and the envelope right and everything else is decoration.

Pick a size that fits an envelope

The single most useful habit in cardmaking is to design around an envelope you can actually buy or make. The most popular size is the A2 card, which finishes at 4.25 by 5.5 inches (about 108 by 140 mm) and slips into a standard A2 envelope. You get an A2 base from a single sheet of US Letter cardstock: cut an 8.5 by 11 inch sheet in half to 5.5 by 8.5, then fold it to 4.25 by 5.5. Other common sizes are A6 and A7, used for invitations. If you would rather start from the card and work outward, the card & envelope size calculator gives you the envelope and the flat blank to cut for any finished size.

Choose a proper card weight

A card base needs to stand up on a mantelpiece, so reach for cover-weight cardstock, roughly 216 to 300 gsm (about 80 to 110 lb cover). Lighter text-weight paper flops over; much heavier board is hard to fold cleanly by hand. Save the thin, pretty patterned papers for layering on top of a sturdy base rather than for the base itself.

Score, don’t just fold

Heavy cardstock cracks along a fold if you simply bend it, because the fibres on the outside of the bend stretch and split. The fix is to score first: press a blunt stylus along the fold line against a scoring board, creating a shallow groove and a matching raised ridge on the other side. Fold with the raised ridge tucked to the inside of the fold, then run a bone folder along the closed crease to set it. The result is a sharp, unbroken spine instead of a ragged white line. If you do a lot of this, a scoring board pays for itself quickly; a bone folder and a ruler will get you started.

A layout that always works

If you are unsure how to arrange a card, borrow a simple rule designers lean on: layers and a little breathing room. Start with the base, add a slightly smaller panel of patterned paper leaving an even border all around (this is called matting), then place your focal element — a stamped image, a die-cut, a sentiment — slightly off-centre rather than dead middle. Three layers and one clear focal point reads as considered; a dozen competing elements reads as busy. Leave some empty space; it makes everything else look intentional.

Glue and finishing

Use the right adhesive for the job. A glue stick or double-sided tape is clean and flat for paper-on-paper layers; foam squares lift a focal element for a little shadow and depth; a fine wet glue like PVA is best for small embellishments. Whatever you use, keep it away from the edges where it can squeeze out, and press each layer down firmly with a bone folder so nothing peels later.

Plan a batch before you cut

If you are making cards for a set — a run of thank-you notes or holiday cards — work out how much cardstock you need before you start cutting so you are not one sheet short of matching stock. A large parent sheet yields several bases, and the paper quantity calculator will tell you how many pieces come off each sheet and how many sheets the whole batch takes, with a little waste built in.

That is genuinely the whole foundation: a base sized to an envelope, cut from cover-weight stock, scored rather than bent, and decorated in a few clean layers. Master that and you can copy almost any card design you admire, because the structure underneath is always the same.
