Frequently Asked Questions
What are the standard dimensions of an A7 wedding invitation suite?
An A7 suite consists of: A7 Outer Envelope (5.25" × 7.25\"), Main Invitation Card (5\" × 7\"), A2 RSVP Card (3.5\" × 5\"), A2 Return Envelope (4.375\" × 5.75\"), and Details/Reception Enclosure Card (4\" × 6\" or 3.5\" × 5\").
How much USPS postage does a wedding invitation require?
A standard 1-oz rectangular invitation requires a 1-oz Forever Stamp ($0.73 in 2026). If your suite weighs over 1.0 oz (due to multiple cards, heavy 120lb stock), or includes a wax seal / ribbon, it requires a 2-oz stamp ($1.01) plus a $0.44 non-machinable surcharge ($1.45 total).
How long should a Maid of Honor or Best Man wedding speech be?
The sweet spot is 3 to 5 minutes (approximately 450 to 650 spoken words at a conversational pace of 120 WPM). Any speech longer than 6 minutes risks losing the attention of guests.
