If you’re wondering how to calculate postage costs for your wedding invites, this guide will walk you through everything you need to know, including domestic and international postage, weight considerations, and how to avoid costly mistakes.
Wedding invitations are often heavier and more delicate than standard mail.
Sending your invites
Failing to calculate postage correctly can result in returned invitations or guests being asked to pay insufficient postage on delivery (not the surprise you want!). Before calculating postage, assemble one full invitation exactly as it will be mailed.
STEP ONE
The most accurate way to calculate wedding invitation postage is simple:
Take one fully assembled invitation to your local post office and have them weigh and measure it.
STEP TWO
At the post office, ask for the following details:
- Whether it qualifies as standard letter mail
- The weight
- The domestic postage rate
- The international postage rate (if applicable)
DOMESTIC SHIPPING
For domestic mailing, postage costs are usually determined by:
- Weight
- Envelope Size
- Thickness
- Shape
Your post office will tell you exactly how many stamps are required per envelope.
INTERNATIONAL SHIPPING
For international mailing, postage costs are usually determined by:
- Destination Country
- Weight
- Envelope Size
- Thickness
- Shape
Your post office will tell you exactly how many stamps are required per envelope.
CALCULATING THE TOTAL COST
Once you know the per-invite cost, multiply it by:
- Total number of invitations (not guests)
- Plus extra copies (always order 5–10 extra)
- Plus RSVP return postage (particularly if you are including stamped RSVP envelopes)
Don’t forget to factor in international postage separately.
FINAL THOUGHTS
When it comes to calculating postage costs for wedding invitations, guessing is never worth the risk. Certainly the most reliable method is to assemble one complete invitation and take it directly to the post office for weighing and confirmation of both domestic and international rates.
This simple step ensures your beautiful invitations arrive safely, on time, and without surprise fees.
