How Many Stamps Are in a Book, and What Does It Cost?
A standard book of Forever stamps holds 20 stamps. As of July 12, 2026, a book of 20 has a face value of $16.40, because each Forever stamp covers the $0.82 one-ounce First-Class Mail letter price. Panes usually hold 20 as well, while coils (rolls) hold 100.
Inside a Book of Stamps: 20 Stamps on Two Panels
A standard USPS booklet of Forever stamps holds 20 stamps, and the count is the same whether the design is a flag, a holiday wreath or a flower. The cover usually prints the count in small type, such as "20 First-Class Forever Stamps" or "Twenty First-Class Forever Stamps," so you can confirm it without counting.
The 20 stamps don't sit on one strip. A booklet is a folded piece of self-adhesive stamps split across two panels, typically 12 on one side and 8 on the other, with the cover and barcode sharing the smaller panel. If you count only the side facing you, the book looks short, so check both panels before you throw away what seems to be an empty cover.
Our US All Season Flags booklets show the layout clearly. The same flag flies in front of trees through four seasons, from bare branches to autumn color, and the four designs repeat across both panels, so one book holds five full sets.
A few issues break the 20-stamp rule. Some older booklets held only 10 stamps, and a few character sheets, which are panes rather than books, hold 12 or 16. When a cover or listing shows a different number, plan your mailing around that number instead of assuming 20.
How Much Is a Book of Forever Stamps in 2026?
A book of 20 Forever stamps costs $16.40 at face value as of July 12, 2026. That's 20 stamps at the $0.82 one-ounce letter price on the USPS price list, and it's what a standard book costs at a post office counter or on usps.com, since USPS sells postage at face value.
Before July 12, 2026, the letter price was $0.78, so a book of Forever stamps cost $15.60. The price of a book of Forever stamps always works out to 20 times the current one-ounce letter rate, so it moves every time USPS changes that rate.
Stamps you already own keep pace on their own. A book bought for $15.60 before the July 2026 increase now covers $16.40 worth of one-ounce letters, and the first Forever stamps, sold at 41 cents in April 2007, still mail a one-ounce letter today. Our guide to what a Forever stamp is worth goes deeper on single-stamp value.
The cost of a book of Forever stamps and other counts follows the same math, at July 12, 2026 prices:
- Book or pane of 20 Forever stamps: $16.40
- Half a book, 10 Forever stamps: $8.20
- Pane of 20 two-ounce stamps: $22.20
- Pane of 20 postcard stamps: $13.00
Books, Panes and Coils Compared
Many Forever designs come in more than one format, and each format holds a set number of stamps. A book folds to pocket size, a pane lies flat as one sheet, and a coil winds the stamps onto a roll.
| Format | Stamps | Face value, July 12, 2026 | Best for |
|---|---|---|---|
| Book (booklet) | 20 | $16.40 | Occasional home mail |
| Pane (sheet) | Usually 20 | $16.40 for 20 | Invitations, matching sets |
| Coil (roll) | 100 | $82.00 | Desk mailing runs |
| Large coil | 3,000 or 10,000 | $2,460 or $8,200 | Machine-stamped office mail |
Panes, also called sheets, usually carry 20 stamps with plate numbers printed in the margins. In our catalog, most love, wedding and commemorative designs come as panes, while holiday designs mostly come as booklets.
A pane is the easier format when you want every envelope in a stack to match, or when you're stamping at a table and want all 20 in view. A booklet travels better in a bag or a kitchen drawer, and a coil wins once you're stamping dozens of envelopes at one sitting.
We run the shop independently of the Postal Service, and every booklet, pane and coil we list is unused surplus postage that we've checked by hand and under UV light. You can browse our current books of Forever stamps by design.
Coils of 100: When a Roll Beats Five Books
One hundred Forever stamps cost $82.00 at face value as of July 12, 2026, whether they come as one coil of 100 or five books of 20. A coil doesn't change the price per stamp; it changes how fast you can stamp a pile of envelopes.
A coil feeds stamps off a single roll, so you peel one, stick it and pull the next without flipping booklet panels. If you send invoices, statements or a newsletter in batches, keeping rolls of Forever stamps on the desk is quicker than working through five booklets.
Our 2026 US Flags stamps come in coils of 100 as well as booklets and panes of 20. The design is a photograph of a knit flag, a detail from a 1989 Polo Ralph Lauren sweater, set above 1776 and 2026 for the nation's 250th anniversary.
Some flag issues, the 2026 design among them, also come in coils of 3,000 and 10,000. Those sizes suit offices that stamp mail by the thousand, often by machine. For a household or a small office, 100 is the practical size.
The tradeoff is commitment, since a coil is 100 identical stamps. Forever stamps don't expire, so leftovers keep their value, but if you want a seasonal design on cards and a flag on bills, two or three books will suit you better than one roll.
How Many Books of Stamps Do You Need?
With 20 stamps in a book, the count is simple: divide the number of pieces you're mailing by 20 and round up. The arithmetic is easy, and most shortfalls come from counting envelopes instead of counting postage.
- Count every piece that needs a stamp: outer envelopes, reply envelopes and any thank-you notes going out later.
- Weigh one finished piece with everything inside. Up to one ounce takes one Forever stamp; heavier letters need more postage.
- Check the shape. Square, rigid or lumpy envelopes pay the nonmachinable surcharge.
- Sort the list into groups: one-ounce domestic, heavier, nonmachinable and international.
- Divide each group by 20 for books or panes, or by 100 for coils, and round up.
- Add a few spares for addressing mistakes and late additions to the list.
Some quick numbers for one-ounce mail: 45 cards take three books and leave 15 stamps spare, 60 cards take exactly three, and 95 letters take five books or one coil of 100.
A letter can weigh up to 3.5 ounces; heavier mail goes as a large envelope, also called a flat. Large envelopes start at $1.69 for one ounce as of July 12, 2026, so a single Forever stamp never covers one.
Wedding Invitations: Count Stamps by Weight
A wedding suite with an invitation card, reply card, reply envelope and insert can pass one ounce, and an underpaid envelope may come back to you or reach a guest with postage due. Weigh one fully assembled invitation before you buy any stamps.
If it lands between one and two ounces, one two-ounce stamp covers the $1.11 two-ounce price as of July 12, 2026, which is neater than doubling up Forever stamps.
Reply envelopes need their own postage. One hundred invitations with stamped replies means 100 outer stamps at whatever the invitation weighs, plus 100 Forever stamps for the replies, which is five books or panes.
The invitations are rarely the only round. Save-the-dates go out earlier and thank-you notes follow the wedding, and both are often one-ounce mail, so a guest list of 100 can call for three separate batches of stamps.
Our Wedding Blooms Two Ounce panes of 20 carry a painted bouquet with TWO OUNCE printed on each stamp. They were issued in 2024 alongside a matching one-ounce design, so the outer envelope and the reply envelope can carry the same look.
Holiday Cards: Planning Books for a Card List
Holiday cards are the simplest mailing to plan in books. A single card in a standard rectangular envelope usually stays under one ounce and takes one Forever stamp, so count your list, divide by 20 and round up. Weigh one first if you add photos or a letter.
Three kinds of card need something other than a Forever stamp from a book, at July 12, 2026 prices:
- Square envelopes pay the nonmachinable price, $1.31 for one ounce.
- Cards going abroad need a Global Forever stamp, $1.75 for a one-ounce international letter.
- Postcards pay the $0.65 postcard price only if they're rectangular, 3.5 x 5 to 4.25 x 6 inches, and 0.007 to 0.016 inch thick; bigger cards pay the letter price.
Global Forever stamps in our catalog come in sheets of 10 rather than 20, so divide an overseas list by 10. Our comparison of Global and domestic Forever stamps explains which mail needs which.
Most holiday designs we carry come in booklets of 20. Our Holiday Wreath booklets carry four wreath designs from 2019 repeating through the book, which suits a list that mixes family, friends and business contacts.
Round up rather than down when you buy. Leftover holiday stamps aren't wasted: as Forever stamps, they cover a one-ounce letter in July just as they do in December.
