How to Size and Print Custom Belly Bands That Fit
Jordan is our labels, packaging and sustainability voice, built from the knowledge of our production team, with over 20 years in printing.
A belly band makes a loose stack of paper look like one finished piece. The sizing formula comes first, then the stocks that survive four bends, and then the three ways to actually buy one.
A belly band is a printed paper strip that wraps the middle of a piece and holds it together. Size it with one formula: flat length equals twice the piece width, plus twice the stack thickness, plus half an inch of glue overlap and an eighth of an inch of ease. Band height runs about a quarter of the piece height, so a 5 by 7 inch invitation suite takes a band 10.75 by 1.75 inches. Our catalog has no product called a belly band, so you order it as a custom die-cut strip, as a bookmark-sized strip, or as a packaging sleeve.
Quick answer
Test the length on scrap before you order
The band is a rectangle, and its length is a wrap measurement rather than a design choice. Cut a strip of scrap paper to the length the formula gives you, wrap the real piece, and adjust before you order a run.
What a Belly Band Does, and What It Is Not
A belly band holds things in register. Drop a wedding invitation, a response card, a details card and an envelope into a box loose and they arrive as a shuffled pile. Put a band around the middle and the set stays square, in order, and reads as one object rather than four.
That job explains most of the design rules. The band only needs to be strong enough to resist sliding, so weight is not the point. It needs to grip evenly across its height, so a band under an inch tall on a large piece looks accidental. It gets removed, usually once, by someone whose hands are already full, so anything that has to be torn or unpicked is a mistake.
Three things get called belly bands and only one of them is. A packaging sleeve covers most of the face of the product. A wrap label is adhesive and sticks to the item, so removing it leaves residue. A belly band touches nothing but itself: it is a plain strip closed on the back with a glue dot, and the piece inside comes out clean. If you are still deciding which of the three the job wants, our guide to the nine types of packaging lines them up next to cartons and mailers.
Where they earn their keep: invitation suites, soap and candle bars, notebooks and journals, folded linens, subscription box contents, hotel amenity sets, and any retail item where the manufacturer wants the product visible and the branding legible at the same time. The full packaging printing collection covers the rest of the box once the band is settled.
The Belly Band Sizing Formula, With the Numbers Worked Out
Each term in the formula has a job. The two widths cover the front and back, the two thicknesses cover the edges of the stack, the half inch is the glue overlap, and the eighth of an inch of ease lets the band slide on without bowing the card.
Work a real one. A 5 by 7 inch flat suite, stacked a sixteenth of an inch thick: two fives make ten, two sixteenths make an eighth, the glue tab adds half an inch, ease adds another eighth, and the band is 10.75 inches long. Height at a quarter of seven inches is 1.75 inches.
The thickness term is the easy one to get wrong. Measure the finished suite, not the invitation card: the suite is a card plus two inserts plus an envelope, which stacks nearer an eighth of an inch and adds a full sixteenth to the wrap. A band cut short does not close, and there is no fixing it after the fact. Stack the real set, hold a ruler against the edge, and use that number.
| Piece | Wrap width | Stack thickness | Band height | Flat band length |
|---|---|---|---|---|
| 5 x 7 in flat suite | 5 in | 1/16 in | 1.75 in | 10.75 in |
| A7 folded invitation, 3 inserts | 5.125 in | 1/8 in | 2 in | 11.125 in |
| 4-bar card, single sheet | 3.5 in | 0.02 in | 1.25 in | 7.665 in |
| Soap bar, 3.5 x 2.25 x 1 in | 3.5 in | 1 in | 1.5 in | 9.625 in |
| 5.5 x 8.5 in notebook | 5.5 in | 0.35 in | 2.5 in | 12.325 in |
The quarter rule is for flat paper. The soap bar and notebook bands run taller on purpose, because there the band also carries the product name.
Two adjustments are worth knowing. If the band will be slid on and off rather than glued around the piece, raise the ease from an eighth to a quarter of an inch, because a slip band that needs persuading will tear at the seam. If the piece is soft, a folded towel or a bundle of napkins, drop the ease to zero and let the band compress it slightly, otherwise the wrap sags.
Folded invitations stack thicker than flat ones at the same trim size, which changes the band length before you have printed a thing. Our comparison of folded and flat invitations covers what that does to the rest of the suite, and the sizes themselves live on flat wedding invitations.
Stock, Grain, and the Cracking Nobody Warns You About
A belly band bends four times. Those four corners are where a good design goes wrong, and the reason is the coating rather than the paper.
Coated stock carries a mineral layer on top of the fiber. Bend it and the fiber creases while the coating splits, which is the white line you see along the fold of a gloss business card. Uncoated and kraft stocks have no separate layer to split, so they crease gray and the crease reads as a fold rather than damage, even on the thicker boards.
Weight sets the second rule. Every stock on our strip products is cover weight, and the heavier the board, the harder it fights a fold. The die-cut strip has no scoring option, so score the two fold lines and the two spine lines yourself with a bone folder and a ruler before you wrap.
Grain runs a distant third but it decides how the flat panels sit. Paper folds cleanly along the grain and fights you across it, so on a belly band the grain wants to run parallel to the fold lines, which means along the height of the strip rather than its length. You cannot choose the grain direction on a short run, so the practical fix is the same: score the folds, and the grain stops mattering. If you want to test a scrap, bend it both ways and keep the direction that curves smoothly.
Coating follows the same logic. High Gloss UV is an option on the die-cut strip and on bookmarks, and a hard coating can crack along a fold, so keep it for art inside the middle third of the front panel, where the band stays flat. Kraft bookmarks show what an uncoated strip looks like in the hand, and our breakdown of cardstock weights in points explains why 14pt and 16pt behave so differently at a fold.
How to Order a Belly Band When There Is No Belly Band Button
What you are buying is a printed strip in a size you specify, so you order it through a product that lets you choose the size.
Route one, the custom strip. Any Shape Size Paper Die-Cut starts at $87.00 for 50, in 16 sizes from 2 x 2 to 11 x 11 inches or a custom size, on 32 stocks from 80# gloss cover through 18pt recycled kraft and metallic pearl. It also cuts a band with a shaped edge. A band longer than 11 inches, like the notebook band in the table, is longer than the largest size on the order form, so join two strips at the back seam.
Route two, the bookmark trick. Standard Bookmarks come in 2 x 6 and 2 x 8 inches on 20 stocks and start at $16.48 for 50. The 2 x 8 strip reaches around a 4-bar card, but not a soap bar or a 5 by 7 suite, so check your number against the table above first. Of the three routes, it is the cheapest way to test a design.
Route three, the finished sleeve. Packaging Sleeves start at $438.25 for 100 in one 5 x 5 inch die-cut size, on 7 stocks from 80# gloss cover to 16pt gloss and 14pt white linen. It fits a disc or a small square pack, not a long piece.
Set the file up like any other print job. Full bleed art needs an eighth of an inch past the trim, and type needs to sit an eighth of an inch inside it, because a strip this narrow makes a crooked trim obvious in a way a postcard never does. Mark the fold positions on a separate layer rather than printing them. The blank template library gives you correctly sized artboards to start from, and how online printing works walks the file from upload to delivery.
Closing them is the last decision. Glue dots are faster than tape and hold better on uncoated stock; double sided tape is cleaner on gloss. Put the seam on the back, centred, so the front panel stays unbroken. Never staple a band, and never glue it while the piece is inside unless you are prepared to lose a few to squeeze-out.
Wally explains belly bands
Twice around, plus the glue tab
Wally stacks the whole suite first, card and inserts and envelope together, then runs a ruler along the edge for the thickness. Twice the width, twice that thickness, half an inch for the glue tab, an eighth of an inch of ease. He marks four score lines so the corners fold instead of cracking, glues the seam on the back where nobody looks, and slides the suite in. The band that fits is the one measured around the finished stack, never around the card.

The three ways to buy a band, side by side
Each of these prints the strip a different way. The die-cut strip ships in 1 to 5 business days, bookmarks can ship the same day, and sleeves take 5 business days. Configure the size, stock and quantity to see the exact price before you order.
Print it
Order the strip that fits your wrap
All three print full color on the front. The die-cut strip and the bookmarks can also print the back in color or in black, which suits a band whose seam side carries a message.

Common Questions
Your belly band questions, answered
What paper should a belly band be printed on?
For a band that bends easily, the two lightest stocks on the die-cut strip: 80# Gloss Cover or 100# Silk/Matte Cover. For a band that feels like board, 14pt to 18pt uncoated cover, or the 18pt Kraft Uncoated Cover made from 100% post-consumer waste.
Do you glue a belly band or leave it loose?
Both work and they solve different problems. A glued band is closed with a glue dot or a strip of double sided tape on the overlap, positioned so the seam sits on the back of the piece. It holds a loose stack in register and it cannot be removed without tearing, which is why product packaging uses it. A slip band is cut a little longer, closed the same way, then slid on and off, which suits invitation assembly because the piece goes in after the band is made rather than while the glue is setting.
Can each band carry a different guest name?
On Standard Bookmarks, yes: variable data is an option, so each 2 x 8 inch strip can print its own name or code. On Any Shape Size Paper Die-Cut, a name on each band is variable data: one design plus a spreadsheet or CSV, set up by the team and quoted.
How much do custom belly bands cost?
Through Any Shape Size Paper Die-Cut, 50 strips cost $87.00. If your band fits a 2 x 8 inch strip, Standard Bookmarks cost $16.48 for 50, and Packaging Sleeves cost $438.25 for 100.
What is the difference between a belly band and a packaging sleeve?
A belly band is a narrow strip around the middle that leaves most of the piece showing. A sleeve covers most of the face. Our Packaging Sleeves are sized for a disc or a small flat item, so a band for anything else is ordered as a strip. Choose the band when the product or the invitation is the thing you want seen.
