Number 13 Foil Mylar Balloons: Everything You Need to Know for Your Big Celebration

What Exactly Are Number 13 Foil Mylar Balloons?

These beauties are large foil balloons shaped like the number 13. Most of them tower at 40 inches tall, which is roughly the height of a seven-year-old kid.

They’re made from shiny mylar material that catches light like nobody’s business. Think of them as the statement necklace of party decorations.

The balloons work for way more than just birthday parties:

• 13th birthday bashes (obviously)
• 13th wedding anniversaries
• Company milestone celebrations
• Bar and Bat Mitzvahs
• Lucky number themed events

Why Foil Beats Regular Latex Every Single Time

I learned this lesson the hard way at my nephew’s party.

Latex balloons deflated within hours, looking sadder than leftover pizza. The number 13 foil mylar balloons I’d splurged on? Still standing proud three days later.

Here’s why foil wins:

• Stays inflated for weeks, not hours
• Doesn’t shrivel up like a raisin
• Reflects light gorgeously in photos
• Won’t pop from a gentle brush against the wall
• Looks premium without premium effort

Color Options That Actually Matter

The classic trio dominates the market:

Rose Gold – My personal favorite for sophisticated celebrations. This shade photographs like a dream and works for literally any age or gender.

Silver – The chameleon of party colors. Matches everything from elegant whites to bold neons.

Gold – When you want traditional celebration vibes. Perfect for milestone anniversaries and formal events.

I’ve also spotted rainbow finishes and holographic options from specialty retailers. But honestly? Stick with the classics unless you’ve got a specific color scheme demanding otherwise.

The Size Situation Nobody Warns You About

40-inch balloons are the standard. They’re impressive without being obnoxious.

I measured mine against my dining room doorframe. They reach just below the top of a standard door opening.

But here’s what the product descriptions don’t tell you: The “40 inches” measures the tallest point, not the width. These balloons take up about 2 feet of horizontal space when inflated.

16-inch versions exist for tighter spaces or budget celebrations. They look cute but don’t pack the same visual punch.

For smaller gatherings in apartments or compact venues, the 16-inch works fine. For anywhere else, go big.

Helium vs Air: The Great Debate

I’ve tried both methods multiple times.

Helium makes sense when:

• You want balloons floating elegantly
• You’re creating balloon bouquets
• The ceiling is your backdrop
• You’ve got easy access to helium tanks

Air inflation works better when:

• You’re mounting balloons on walls
• Budget matters (helium costs add up)
• You’re using balloon stands
• The event lasts multiple days

Here’s my honest take: Air-filled balloons on stands or walls look just as impressive as floating ones. Nobody at the party judges your inflation method.

Where to Buy Without Getting Ripped Off

I’ve bought these balloons from practically everywhere.

Walmart typically prices the 40-inch rose gold version around $19.99. The quality matches pricier options perfectly.

Party City offers similar prices with more color variety. Their staff actually know how to help, which matters when you’re confused.

Amazon works great when you’re planning ahead. Search for 40 inch number balloons and filter by reviews.

Dollar stores sometimes stock 16-inch versions. Quality varies wildly, but for quick decorations, they’ll do.

Skip the grocery store party section. Prices run higher for identical products.

Creating Killer Displays That Look Professional

My first balloon arrangement looked like a toddler sneezed glitter.

After several parties, I’ve cracked the code.

The Classic Float:

• Attach curling ribbon to your helium-filled numbers.
• Add weighted bases in coordinating colors.
• Cluster smaller latex balloons around the base.
• Done.

The Wall Statement:

• Secure your air-filled numbers using balloon glue dots.
• These sticky circles hold balloons to walls without damage.
• Surround the numbers with chrome balloons in various sizes.
• Add star-shaped mylar balloons for dimension.

The Arch Framework:

• Position your 13 as the focal point.
• Build out from there using balloon strips.
• Alternate colors and sizes for visual interest.
• Secure everything with fish line tied to furniture or hooks.

Pro combinations that always work:

• Rose gold 13 + white latex + gold confetti balloons
• Silver 13 + black latex + star shapes
• Gold 13 + burgundy latex + ivory accent balloons

Inflation Tips Nobody Tells You

The valve on foil balloons frustrated me endlessly at first.

For helium inflation:

• Push the tank nozzle firmly into the valve opening.
• Hold the balloon neck taut while filling.
• Stop when the balloon feels firm but not drum-tight.
• Over-inflation causes seam splits.

For air inflation:

• A hand pump works, but your arm will hate you.
• Invest in an electric balloon pump.
• These devices cost around fifteen bucks and save
