Happy birthday bubble letters

How do you write Happy Birthday in bubble letters?

Write the words as a light pencil skeleton with wide gaps, inflate each letter into a soft round shape, then fill, outline and shade. Happy Birthday has 13 letters, so the whole trick is planning the space before you draw anything big. These steps work on a card, a poster or a whiteboard.

1. Measure the space first. Lightly mark the left and right edges and the height you want. For a folded card, letters about 2 cm (3/4 inch) tall fit on two lines. On a poster, go for 8–10 cm (3–4 inches) so the words read from across the room.
2. Write the skeleton in pencil. Print HAPPY and BIRTHDAY in thin single lines, all the same height. Leave about a letter's width between letters, because each one is about to get much fatter. Start with the middle letter of each word (the first P in HAPPY, T and H in BIRTHDAY) and work outward, so the words come out centered.
3. Space the two words. On one line, the gap between HAPPY and BIRTHDAY should be wider than the gaps inside the words, about one full bubble letter wide. Otherwise it reads as one long word.
4. Plan the p's and y's. In capitals, every letter sits on the line. In lowercase, the p, p and y in "happy" and the y in "birthday" drop below it. Leave room under the line, or switch to capitals if the card is short. The bubble letter Y and P pages show both forms.
5. Draw the bubbles. Trace around each skeleton letter about a finger-width out and round every corner. Let neighbors touch or tuck slightly behind each other. Erase the skeleton.
6. Color, outline, shade. Fill first, then go around each letter with a thick black marker, then add a 3D block on one side and white highlight marks. The full method, with pictures for each step, is in the bubble letters guide.

Keep everything in pencil until the spacing looks even. Ink is the last step, and it is the only one you cannot erase.

Happy birthday layout: one line or two?

Use two lines for anything taller than it is wide, like a card, a sign or a cake topper, and one line for long banners. Two lines let each letter be bigger. HAPPY is shorter than BIRTHDAY, so center it over the second line or make its letters a little larger so both lines end up the same width.

• Stacked: HAPPY on top, BIRTHDAY underneath, the name on a third line. The easiest layout to get right.
• Curved: on a banner or poster, draw a gentle arc in pencil and stand each letter on it, tilted to follow the curve. Keep the arc shallow or the end letters lean too far.
• Bouncing: lift every second letter a little above the line. It looks playful and hides small size differences.
• With the age: put a big number to the right of both lines, or under BIRTHDAY in place of the name. Draw it in the same bubble style; see graffiti numbers for digits.

Leave a margin of empty space around the words for balloons, stars, confetti dots or candles. A crowded edge makes bubble letters look squashed.

Happy Birthday in graffiti styles

Bubble letters are the classic choice, but Happy Birthday works in any graffiti style. Tap "Make this" to open the same words and style in the generator, change the colors, and download it as a PNG or SVG.

For older kids and teens, a throw-up or wild version looks more like real street graffiti. The graffiti styles page explains how each one is built.

How do you add a name or age to Happy Birthday?

Put the name on its own line under BIRTHDAY, in the same bubble style but in a different color so it stands out. For an age, a large bubble number beside or below the words works best. In the generator, type the full line, such as "Happy Birthday Mom", and it lays out the letters for you.

Long names fit better on a line of their own. To try a name in other styles, open it in the generator and switch styles in the Style tab.

Printable Happy Birthday banner letters

The free banner PDF spells HAPPY BIRTHDAY with one big bubble letter outline per page, 13 pages in total. Print it, color the letters, punch two holes at the top of each page and string them up. The pages fit A4 and US Letter.

1. Print with "Fit to page" on. The pages are A4; on US Letter this setting keeps the edges from being cut off.
2. Use cardstock if you can. Thick paper (65–110 lb) hangs flat, does not curl when you color it with markers, and survives a party.
3. Color, then cut. Color the letters first, then cut around each one, leaving a thin white border outside the black line.
4. Punch and string. Punch two holes near the top of each letter, about 2 cm in from the sides. Thread ribbon, yarn or baker's twine through the front of one hole and out the back of the other, so the string stays hidden.
5. Hang in two rows or one. One long string needs about 3 meters (10 feet). For a doorway or a smaller wall, hang HAPPY and BIRTHDAY on two strings, one above the other.

To add a name or an age, print those letters from the printable bubble letters alphabet and numbers PDFs. They use the same style, so the banner matches.

Birthday card ideas with bubble letters

A bubble letter card needs only a folded sheet of cardstock, a pencil, a black marker and two or three colors. The lettering is the decoration, so keep everything else simple.

• Pop-out front: draw HAPPY BIRTHDAY on cardstock, cut it out and glue it to the card on small foam squares so it stands off the page.
• Favorite colors: fill each letter in the birthday person's favorite color, or one rainbow color per letter.
• Pattern fill: stripes, polka dots or tiny hearts inside the letters look fancy and are easy for kids.
• Inside message: the front says HAPPY BIRTHDAY, and the inside has the name or age in big bubble letters.
• Printed and colored: download a PNG from the generator, print it at card size, and color or glue it on.
