Invitation video size, length and format for phones and WhatsApp

Short answer

Export your invitation video as a vertical MP4 at 1080p, between 15 and 30 seconds long, and keep the file under 40 MB. Make sure the words can be read with the sound off.

What size and shape should it be?

A vertical frame, 1080 by 1920 pixels, fills a phone screen without bars. Most guests will open the invitation on a phone, so design for that first. A square or a wide frame still works, but it shows smaller on a phone and the text gets harder to read.

How long should it be?

Between 15 and 30 seconds. Longer files are larger and slower to open, and guests rarely watch beyond that before they look for the date. If you have a lot to say, put it on the page, where it can be read at the guest's own pace.

Which file format is safest?

MP4 is the safest choice. CardToPage accepts MP4, MOV and WebM, up to 40 MB each. In your editor, an MP4 export with the common H.264 video setting plays on nearly every phone and browser.

Why does the text look soft after sending on WhatsApp?

Messaging apps often compress a video that is sent as a message, to save data. Small text suffers first. Sending a link to a page that holds the video avoids that kind of compression, and the guest also gets the reply form and the map on the same screen.

How do I keep the words readable?

• Put the most important words in the first two seconds: the names and the occasion.
• Keep the text away from the top and bottom edges, because a phone's own buttons can cover them.
• Leave each line on screen for at least two seconds.
• Use large, plain letters for the date and the time.
• Watch it once on a real phone with the sound off.

What if the file is too big?

Export again at a lower quality or a shorter length, and then watch the smaller copy to the end. If the date or the venue text is blurry, go back one step in quality.

What belongs on the page instead of the video?

The full address, the Directions button, the RSVP form, a Call button, the countdown and Add to calendar. They can be fixed after you send the link. Words inside a video cannot.
