Sending letters by mail can be a bit tricky when it comes to the number of stamps you should use.

This number relies on several factors. But, more importantly, it depends on the overall weight of your letter.

So, how many pages can you mail with one stamp?

**Generally speaking, you can mail between 4-6 sheets of standard paper. However, this only works out if the overall weight of your envelope is below 1 ounce.**

A bit confused? Let’s dive a little deeper.

## Why You Should Calculate the Right Number of Stamps Per Letter

Some people might not be aware of the exact number of stamps that they should include on their letters. Since they don’t know the postage rate of their letters, they might end up costing themselves extra money without realizing it.

The thing is, this additional money won’t return to you if you overestimate the postage price.

You might argue that it’s only a difference of a few cents. However, in the long run, each cent will add up, which could be wasteful.

Fortunately, there are a few ways you can make sure this doesn’t happen.

## What Is Postage Rate?

Now, before you learn how to calculate the correct number of stamps per letter, you must know what the postage rate is.

Simply, the postage rate is the amount of money charged by the postal service to ship and deliver your mail. The postage rate can highly differ depending on many factors.

Therefore, you need to make sure that you understand each variable before sending out mail. This way, you’ll be able to estimate how much money you’ll be spending.

You can determine the price of your mailed letter or package by paying attention to the following factors.

- The minimum postage rate
- The weight of your letter or package
- The class of the item you’re mailing
- The type and size of packaging or envelope

## How to Know Your Postage Rate

The postage rate can differ from one year to another. And without some background knowledge of it, you won’t be able to estimate the cost of your letters accurately.

Luckily, there are postage rate charts that you can take a look at to know how much you’ll be charged. These can be of great help once you try to calculate the overall cost of the letter you need to mail.

Also, these guides contain all the data you may need about package shipping costs, international mail costs, priority mail, etc.

This way, you can always refer to these charts before sending anything in the mail.

## Postage Rate and Letter Weight

Ultimately, the weight of your letter is the topmost determiner of how many stamps you should include. For instance, a 1-ounce letter costs 55 cents to mail. In this case, it’s called a first-class mail letter.

For each additional ounce, you’ll be charged 15 cents. But again, this only works if you’re using a traditional envelope.

On the other hand, if you’re mailing your papers in a flat/large envelope, the cost will be a bit higher. In this case, a 1-ounce letter will cost you 1 dollar. With each extra ounce, you’ll need to add 20 cents to the overall price.

Yet, figuring out the weight of your letter may not be easy since there are many factors at play here. You’ll need to calculate the weight of the envelope and the weight of the papers themselves.

Luckily, there are ways to do both effortlessly.

## Measuring the Weight of Your Letter

Undoubtedly, getting an accurate measuring of your letter’s weight will help you determine the number of stamps needed. Since this will give you an estimation of the postage cost, there’ll be no room for surprises.

Now, how can you measure the weight of your letter?

### Go to Your Nearest Post Office

Every post office in the US has a scale, which should make your task a lot easier.

Simply enough, you can take all the types of paper and envelopes that you wish to use to the nearest office. Then, you can experience with combinations of both until you figure out the right blend.

Still, not everyone resides near a post office. In fact, you may be too busy to pay the post office a visit. In this case, we suggest that you use another method.

### Figure Out the Standard Letter Paper Weight

Another effective way to calculate the weight of your letter is to know how the paper you’re using normally weighs.

For example, letter paper is usually sold in reams, with each ream containing about 500 pieces of paper. Also, the weight of an entire ream is usually written on it. Yet, it isn’t as simple as it may seem.

Usually, the weight written on each ream can be inaccurate. It indicates the overall weight of the paper before being cut into the size of a letter. Therefore, you should make calculations of your own.

We’ll spare you all the details and only point out that the weight that’s written on a ream of paper is often four times more than what you really have. For instance, if you see that the given weight is 24 lbs, then you’ll know that the physical weight of the paper is only 6 pounds.

Now that you know how much an entire ream of letter paper weighs, you can easily figure out the weight of each individual piece of paper. However, don’t forget to convert that weight to ounces.

### Weigh Your Envelope at Home

You may find the previous method tough. It requires a lot of calculations, which you may not have the spare time to do.

For this reason, we encourage you to use a sensitive scale, which you might already have at home. Luckily, ordinary kitchen scales have the ability to register the weight of envelopes in grams or ounces.

For larger packages or boxes, you can use a typical bathroom scale.

Either way, you’ll need to round out the resulting weight of any item to the nearest ounce.

## Estimating Your Postage Fees

If you’ve already figured out the overall weight of your envelope by using a scale, the rest should be a piece of cake.

Yet, if you’re using the second method that you’ve mentioned above, you’ll have to calculate a few extra things.

Now that you have a clear idea of how much each paper weighs, you can multiply this weight by the number of papers that you intend to use.

For instance, if each paper weighs 0.16 ounces and you want to use ten papers, then the overall weight will be 1.6 ounces. You should also give some room to the envelope weight, which may leave you with a total of 2 ounces.

As we’ve discussed before, you should get one 55-cent stamp if your letter weighs less than 1 ounces. In our case, you may consider purchasing two first-grade stamps, which may not be the best idea.

Fortunately, you’ll find other stamp types at the post office. One, in particular, will only cost you 15 cents, which is what you exactly need at this point.

Therefore, to mail these ten papers, you’ll need only two stamps, a 55-cent stamp and a 15-cent stamp.

Of course, you can use this method whenever you need to mail a letter that weighs more than 1 ounces. All you have to do is add a 15-cent stamp for each additional ounce above the 1-ounce mark.

## Understanding Value Stamps

Aside from these handy 15-cent stamps, you can find more options at the post office. These value stamps can give you the chance to cover additional ounces without the need to pile up unnecessary 55-cent stamps.

This way, you won’t be overspending your money on mailing letters or packages.

## Using a Postage Price Calculator

Using a postage price calculator can spare you a lot of time and effort. All you have to do is enter all the data related to your letter, package, or shipment.

This information includes:

- Your Zipcode
- The destination country or the Zipcode of the location you’re mailing to
- The date and time when you plan to mail your letter
- The type and class of the item you’re mailing

Then, this tool will calculate the postage price for you after you provide it with the dimensions and weight of your package.

The best thing about this service is that it works with almost all types of shipments. You can use it to calculate the price of postcards, flat rate envelopes, boxes, and more.

## To Wrap It Up

How many pages can you mail with one stamp?

Since one 55-cent stamp is needed for a 1-ounce letter, you’ll probably end up mailing 4-6 pages of letter paper.

Of course, after reading our article, you’ll understand how we got that result. It mainly depends on the weight of your envelope, which you should be aware of before mailing it.

Once you are, you can use one of the many methods that we’ve addressed to figure out how many stamps you’ll need.
