A DIY birthday banner made of craft paper stays straight when every letter gets its own pennant instead of sharing one long strip. Cut each pennant 6 inches wide and 7 inches tall, leave 1 inch between neighbours and 4 inches between the two words, and Happy Birthday measures 93 inches. With 12 inches of spare cord on each side, that is 117 inches of cord. I plan every banner from those numbers before I touch a sheet of paper.
Most pages show how to paint or glue the letters. Almost none give the size of one cell, the length of the cord or the paper weight in both systems, so the line gets judged by eye. Here is the arithmetic instead.
Quick answer: one letter, one pennant, one cell.
- Cell: 6 inches wide, 7 inches tall, the same for every letter.
- Gaps: 1 inch between letters, 4 inches between words.
- Length: 93 inches for Happy Birthday, 117 inches of cord with 12 inches spare on each side.
- Paper: 80 lb cover, which is about 216 gsm.
- Sheets: one pennant per Letter sheet, so 13 sheets.
- File: the Bunting Banner Bundle Pastel Svg gives you PNGs at 300 dpi, so the print stays sharp.
Why a painted strip drifts and a row of pennants does not
Six steps, one piece of paper, about 20 minutes.
It looks great on photos. The catch is that you paint one object. Your letters get squeezed toward the right edge, and a wobble on the last letter spoils the entire strip.
A row of pennants works the other way. Every letter lives on its own sheet, so one bad letter costs you one sheet. The line is set by the cord, not by your eye.
Pro tip: keep the painted strip for a short name on a wall you can reach, and use pennants for anything longer than a name.
Reads from across the room: the cell each letter gets
Give every letter the same cell, 6 inches by 7 inches. A narrow I and a wide W then sit in exactly the same place on the cord, so your line does not wander.
Draw the letter 4 inches tall and centre it. That leaves 1.5 inches above and below on every pennant, and the tops of the letters sit on one invisible line.
- Same height on every pennant: measure it once, on the template.
- Same margin: 1.5 inches of paper above and below the letter.
- Narrow letters stay narrow: do not stretch an I to fill the cell.
A small pennant is the usual trap. A 4.5 inch pennant looks neat in a tutorial, but the letter on it shrinks to a size you only read from a step away. The big cell lets you read the banner from the doorway to the cake table. The Pastel Bunting Banner Bundle lays each letter in its own pennant cell, which is the point of this section.
Paper weight: where 216 gsm sits and what to skip
Pages in this niche name paper weight in grams and in pounds in the same paragraph and never connect the two. The conversion is short:
| Weight in lb (cover) | Roughly in gsm | What it does on a cord |
|---|---|---|
| 65 lb | 176 gsm | Sags between the holes, corners curl in a warm room |
| 80 lb | 216 gsm | Hangs flat and punches clean |
| 100 lb | 270 gsm | Hangs flat, but the punch needs a firm hand |
I pick 80 lb for a banner. If you fold cards from the same stock, the handmade birthday cards by paper weight page covers the same weights.
You will see both spellings, craft paper and kraft paper. The brown sheet you want is kraft, and it is sold by weight like any other paper, so check the number before you buy.
Product pages skip the weight, so you decide it yourself. A cut file such as the Bunting Birthday SVG gives you the outline, and the sheet is still your choice.
Pro tip: if the sheet you own is thinner than 80 lb, glue two layers back to back and the pennant behaves like the heavier one.
How long the cord has to be for Happy Birthday or a name
Cord length is plain arithmetic. You count the letters, multiply by the cell width and add the gaps.
- Letters: Happy Birthday is 5 + 8 = 13 letters.
- Pennants: 13 × 6 = 78 inches.
- Gaps: 11 gaps of 1 inch plus one gap of 4 inches between the words, so 11 + 4 = 15 inches.
- Banner: 78 + 15 = 93 inches.
- Cord: 93 + 12 × 2 = 117 inches, with 12 inches spare on each side for the knot and the hook.
Your five-letter name on the same pennants is shorter: 5 × 6 = 30 inches, plus 4 gaps of 1 inch makes 34 inches. With the spare ends that is 58 inches of cord.
Cord length for a pennant banner is the letters × 6 inches, plus 1 inch for every gap, plus 4 inches for the word break, plus 24 inches of spare cord.
Pro tip: mark the gaps on the cord with a pencil before gluing anything. Pennants then go on at marks, not by eye.
The same sums hold for any file you pick. Ten designs in the Bunting Banner Bundle Pastel Svg change the look of the pennant, and your cord stays the same length.
Print it sharp at home: the file size per pennant
A 6 by 7 inch pennant at 300 dpi is 1800 × 2100 pixels. A file smaller than that prints soft at the edges of the letter, and you look at a banner from close up while you hang it.
On a Letter sheet (8.5 × 11 inches) only one pennant fits: a second one beside it needs 6 + 6 = 12 inches of width. Thirteen letters mean 13 sheets, so count your paper before you count the printer ink.
A listing that states the resolution saves you a test print. The Bunting Banner Bundle Pastel Svg lists 10 files in each of four formats, SVG, EPS, DXF and PNG at 300 dpi.
Cut, punch and glue the letters that fall out
Make one pennant from a spare sheet of card and use it as the template for all 13. You trace, cut and stack. If you already score folds for a pop-up card from score lines, the same ruler and bone folder do the job here.
- Trace: mark every pennant from the card template, not from the previous pennant. Copies of copies grow.
- Punch: 0.5 inch down from the top edge and 0.75 inch in from each corner, using the same card template with the holes already marked.
- Cut letters: if you cut letters from a contrasting paper, keep the loose centres in a pile.
- Glue: letters first, centres last, then thread.
A cut file such as the Bunting Birthday SVG gives every outline the same shape, which replaces the tracing step.
The letters A, B, D, O, P, Q and R have islands inside them. They drop out as separate pieces the moment you cut, and they are the ones that get lost or glued upside down.
Pro tip: glue one island to a scrap strip with tape while you cut, so the whole alphabet of loose bits is in one place.
Edit the name, date and age without moving the line
A banner you can edit is a banner where the cell stays the same and only the letters change. You change the name, the cord follows. In Canva that means frames shaped like letters, so you drop the paper or picture into the frame and the size is already set.
The Bunting Party Set Canva Frame Template works this way, and it runs in both the free and the Pro version of Canva.
When you change the name, recompute the cord. A five-letter name needs 58 inches, a thirteen-letter greeting needs 117. The cell does not change, only the count.
A number for the age is one more pennant on the same cell. You add 6 + 1 = 7 inches and move the end knot.
If you want other paper builds in the same evening, the same cell logic carries over to a 3D birthday card made in one evening or to paper crafts for a mom’s birthday.
Bunting files worth opening, sorted by what they solve
You do not need a file for a banner, but a good one removes the drawing step. These three take care of the part that goes wrong first.

If it goes wrong: mistakes that bend the line on the last letter
- Starting at one end: if you start there, every error piles up at the other end. Start from the centre pennants and work outwards, so you split any error in half.
- Tracing from a copy: you trace a copy of a copy and the pennants grow, so always trace from the card template.
- Skipping the pencil marks: without marks on the cord, your gaps drift and the word break disappears. A banner you finish the night before still needs ten minutes for them.
- Forgetting the spare cord: with no 12 inches on each side the banner will not reach the hooks.
- Printing at low resolution: you will see soft letters from the doorway, and they look worse than a hand-drawn line.
Questions about craft paper birthday banners
What paper to use for banner?
Use 80 lb cover, about 216 gsm. It hangs flat on a cord and you can cut it with ordinary scissors. Anything near 65 lb, about 176 gsm, sags between the holes for you.
What type of paper is used for banners?
Kraft paper and cardstock cover most banners. Kraft gives the brown rustic look, cardstock gives clean colour and a sharper edge for print.
How to make a paper banner?
Cut one pennant per letter from a card template, punch the holes in the same place, glue the letters on and thread the cord. Keep the cell at 6 by 7 inches so your line stays straight, and let a letter-shaped frame such as the Bunting Party Set Canva Frame Template do the layout.
How to make a craft paper birthday banner?
Plan the length first: 93 inches for Happy Birthday, 117 inches of cord with the spare ends. Then cut, punch, decorate and thread.
What size is a kraft paper birthday banner?
There is no fixed size. A pennant 6 inches wide and 7 inches tall reads well, and the length follows from the letters: 34 inches for a five-letter name, 93 inches for Happy Birthday.
Key Takeaways
- One letter per pennant keeps the line straight, because one mistake costs one sheet.
- A cell of 6 by 7 inches gives every letter the same place on the cord.
- 80 lb cover is about 216 gsm and is the weight that hangs flat.
- Cord length is letters × 6 inches plus gaps plus 24 inches of spare cord.
