The #10 Envelope is a standard business sized envelope. You can go to a number of different websites to find more information - perhaps you want to create a series of envelopes for various things - I have no idea why, but it's good to have the information.

For your flyer you could go with 4.25" x 5.5" which would essentially be a quartered 8.5x11 paper. Or, any number of different sizes. Long and thin etc. Think about printing possibilities however and cost.

3.5"x2" is the standard size. But again, noone says you have to be standard. Just think about cost and what's the most important factor...
