Envelopes - custom printing

[FV09]

Can anyone help me in trying to print a 5 5/8" wide by 4 3/8" high invitation envelope? These size aren't available under envelopes and labels and the custom size won't allow these dimensions. I would really appreciate some help. Thank you.

Firstly, I'm assuming that your Word is set to inches, not centimetres.

Secondly, you need to use the decimal version of the measurements:
5 5/8" = 5.678"
3 3/8" = 4.375"

Now, choose any size envelope in the Envelopes & Letters dialogue and go through the process to create your envelope. Don't worry that it's not the right size yet.

Once you've finished and got your envelope, click so the cursor is on the envelope and go to File, Page Setup, Paper tab. For height and width here, enter your sizes as above, then click OK. This should resize your page as required.
