US vs European Paper Sizes Explained

You open your template, it says 5 × 7 inches, and your printer's sitting there loaded with A4. Cue a little flicker of "wait, is this going to work?" Good news: it will. marryful templates are set up in US sizes, but they print perfectly well on European paper too — once you know the one thing that actually matters.

The short version

Here's the part most guides bury: the size of your invitation or card doesn't change — only the sheet of paper around it does. A 5 × 7 invitation is 5 × 7 whether you print it on US Letter or A4. The paper is just the tray it travels on, and you trim the card out either way.

US vs European (DIN) sizes

The two systems differ mainly in the full sheet you print on:

US Letter: 8.5 × 11 inches (about 216 × 279 mm) — the standard sheet in the US.
A4 (European DIN): 210 × 297 mm (about 8.3 × 11.7 inches) — the standard sheet across Europe. It's a touch narrower and taller than Letter.

Because A4 is slightly narrower than Letter, a design built for Letter can get nudged or trimmed at the edges if you let the printer "shrink to fit." That's the only real pitfall — and it's easy to sidestep.

How to print the size you need

At home: load whatever paper you have, US Letter or A4, and in your print settings choose 100% / Actual size — never "Fit to page" or "Shrink to fit." Your card prints at its true size with a little extra paper around it, and you trim to the cut lines. Done.

With a print service: Corjl Prints, Prints of Love and local shops handle sizing for you — just pick the size that matches your template, or tell a local printer the dimensions, and they'll sort the paper.

One exception worth knowing: if you specifically want to use pre-cut cards or envelopes that are sized to European (A-size) dimensions, a US-built template won't match them exactly. In that case you've got two choices — accept that some parts of the design may sit a little narrower or get trimmed at the edges to fit, or print on a full sheet and cut to the template's own size instead of forcing it onto EU pre-cut stock. If matching a particular envelope or card matters to you, check its size against your template before you print.

The one rule that fixes 90% of sizing problems: print at 100%, not "fit to page." Fit-to-page is what quietly shrinks a US design onto A4 (or stretches an A-size onto Letter). Turn it off and the proportions stay exactly right.

Paper size questions, answered

Are marryful templates US or European sizes?

They're set up in US sizes, but they print on European (A-size) paper too. The card itself stays the same size; you just print at 100% and trim.

I'm in Europe — can I still use these?

Absolutely. Load A4, print at 100% / actual size, and trim your card to the guide lines. The design comes out exactly as intended.

My design printed slightly cut off. What happened?

Almost always "Fit to page" or "Shrink to fit" in the print dialog. Switch to 100% / Actual size and print again — that's the fix.

Do I need to resize the file myself?

No. Download it as-is and let the print setting (100%) do the work. Resizing the file yourself is what usually throws the proportions off. Downloading is covered here.

Which is better for cards — Letter or A4?

For trimmed cards it makes no real difference — use whichever paper you have. Both give you plenty of room around a 5 × 7 or smaller card.

What if I'm using pre-cut EU cards or envelopes?

That's the one case to watch. The templates are built to US dimensions, so they won't match EU pre-cut card sizes or EU envelopes exactly. If you specifically want to use EU-sized pre-cut stock, the design won't line up perfectly — you'd either accept that some parts sit a little narrower or get cropped at the edges, or print on a full sheet and trim to the template's own size. Check your envelope or card size against the template before printing if an exact match matters.

So: don't worry about the inches-versus-millimetres of it all. Print at 100%, trim to the lines, and your card is the right size no matter which paper it started on.
