Last updated on May 12th, 2022 at 10:15 am

With so many envelope sizes available, it can seem challenging to choose the right one. An A7 envelope is a good option that has many uses.

## Length, Width, and Height of an A7 Envelope

A7 envelopes are 5.25 inches tall and 7.25 inches long. This is equal to about 13.34 centimeters tall by 18.42 centimeters long.

Although the height and length of an A7 envelope are standardized, the width or thickness usually isn’t.

Different envelopes are made of different paper types, and these envelopes might be designed to perform various tasks.

What the envelope was made for and what paper type it uses can change exactly how thick it is.

However, most envelopes are about 6.35 millimeters or 0.25 inches thick. This allows them to hold a thick card or several sheets of folded paper.

## A7 Envelope Weight

Because A7 envelopes can have different thicknesses, and because they can be made of so many different types and thicknesses of paper, it’s difficult to determine exactly how much one will weigh.

However, you can estimate. Most envelopes of this size weigh about 6.75 grams or 0.238 ounces.

This is about 1.5 times the weight of a single sheet of copy paper. Cards, which are printed on much thicker paper, usually weigh around 30 grams or 1 ounce.

If you need to estimate the weight of the envelope and its contents so you can accurately calculate postage, you can use these common weights to estimate, or you can use a small food scale to weigh them.

## What are A7 envelopes used for?

A7 envelopes are one of the most common types of envelopes. They can be used for greeting cards or mailing a letter written on notepaper. They’re also commonly used for fancy or special occasions.

Many people choose A7 envelopes and cards or pictures of matching size to send out wedding invitations, partying invitations, or make announcements about important moments such as engagements or births.

These particular envelopes can have either square or triangular back flaps, but square flaps are more common in this size.

The notable exception to this is for greeting cards, which more often use a triangular flap. Triangular flaps are considered to be more informal, while square flaps, also called wallet flaps, are thought to have a more formal look.

Most flaps have a liquid-activated adhesive that seals the envelope shut, but some have adhesive covered in small strips of plastic, which you can peel away to seal the envelope.

When you’re considering using an A7 envelope, it’s important that the envelope’s size is measured from the outside.

The inside of the envelope will be slightly smaller. Usually, this is a difference of between 0.125 to 0.25 inches all around.

## Selecting the Right Envelope

When it comes to selecting an envelope, choosing the right size is the most important step.

If you have an idea for the card, invitation, or announcement you want to send, you will most likely want to choose an envelope that is at least 5 millimeters or about 0.2 inches larger all around.

If what you’re mailing uses thicker paper, make sure to choose a durable envelope with plenty of space so the items will fit and won’t break through the envelope during travel.

If you’re ordering a large number of invitations or announcement cards, most companies will also let you choose what the envelope looks like and what type and color of paper it uses.

Thicker papers often look excellent, but they can be costly and, unless you need a particularly durable envelope, are usually unnecessary.

The color and design of the envelope are up to your personal preference.

When you place an order for envelopes, make sure to order a few more than you need in case you make any mistakes while writing out addresses.
