How do you address a wedding envelope when the wife is a doctor?

Because professional medical titles outrank social titles, the doctor's name is listed first: 'Doctor Katherine Evans and Mr. Robert Evans' (or 'Dr. Katherine Evans and Mr. Robert Evans'). If both are doctors, write 'The Doctors Evans' or 'Drs. Katherine and Robert Evans'.

Should states and street directions be abbreviated on wedding envelopes?

In formal wedding etiquette, abbreviations should be avoided on outer envelopes. Spell out 'Street', 'Avenue', 'Boulevard', 'Apartment', 'Post Office Box', and the full state name (e.g., 'New York' instead of 'NY'). However, for casual modern weddings, two-letter postal state abbreviations are widely accepted.

Address each person on a separate line in alphabetical order by last name: 'Ms. Jessica Taylor' on line one, and 'Mr. David Miller' on line two, followed by their shared street address.

Q: How do you address an envelope with a plus-one?

On an outer envelope, formal etiquette prefers finding out the guest's actual name. If unknown, write 'Mr. Alexander Clark and Guest'. If using an inner envelope, write 'Mr. Clark' on the outer envelope and 'Alexander and Guest' on the inner envelope.

Q: Where does the return address go on wedding envelopes?

Traditionally, the wedding couple's return address is printed centered on the back flap of the outer envelope. For RSVP envelopes, the return address is printed on the front center of the A2 envelope.

The Complete Guide to Wedding Envelope Addressing Etiquette

Your wedding invitation envelope is the very first tactile impression guests receive. Master envelope sizing, title hierarchies, and postal stamp rules with zero guesswork.

1. Understanding Envelope Sizes: A7 vs A2 vs Inner Envelopes

In wedding stationery, envelope dimensions use standard letter designations. Selecting the wrong envelope size can lead to cramped inserts or invitations that buckle inside:

A7 Outer Envelope (5.25" × 7.25" / 133mm × 184mm): The universal standard envelope for 5" × 7" wedding cards. Leaves a clean 1/8" buffer on all sides to accommodate cardstock thickness, pocketfolds, wax seals, and multiple enclosure cards.
A2 RSVP Reply Envelope (4.375" × 5.75" / 111mm × 146mm): Holds standard 3.5" × 5" or 4.25" × 5.5" response cards. Pre-addressed to the wedding hosts and pre-stamped with a USPS Forever Stamp.
A7 Inner Envelope (5.125" × 7" / 130mm × 178mm): Slips inside the A7 outer envelope unsealed. Specifically names each invited guest (including plus-ones and children) to remove ambiguity about who is invited.

2. Honorifics, Titles & Name Hierarchies

Traditional social etiquette establishes strict protocols for addressing distinguished guests and blended households:

Medical Doctors: Spell out Doctor on outer envelopes (e.g. Doctor Katherine Evans and Mr. Robert Evans). Because a professional degree outranks a social title, the doctor's name always takes precedence regardless of gender.
Military Officers & Judges: Use full rank or title (e.g. Captain James Miller, USN and Mrs. Miller or The Honorable David Vance and Mrs. Vance).
Widows & Divorced Women: Traditionally addressed as Mrs. John Smith (for a widow) or Ms. Sarah Jenkins (for a divorced woman using her maiden name).

3. USPS Postage, Weight & Wax Seal Rules

Before mailing 100+ invitations, always take one fully assembled suite (with wax seal, belly band, and all inserts) to your local post office window to be hand-weighed:

🚨 Important Postal Traps to Avoid:
• 1 oz Weight Limit: Suites weighing under 1.0 oz require 1 standard 1-ounce Forever Stamp. Suites between 1.01 oz and 2.0 oz require a 2-ounce stamp.
• Non-Machinable Surcharge: Wax seals, ribbon knots, rigid acrylic cards, and square envelopes cannot pass through automated sorting rollers and require a Non-Machinable surcharge stamp.
• Hand-Canceling: Request "Hand Canceling" at the post office so a postal clerk stamps the postage by hand rather than feeding delicate calligraphed envelopes through heavy machinery.
