Red Bull Can Dimensions: All Sizes, Height & Diameter

The classic Red Bull can is one of the most recognizable shapes in any cooler: tall, narrow, and unmistakably slimmer than the soda sitting next to it. But “how big is a Red Bull can” has more than one answer, because the brand sells at least five different sizes and they don’t all use the same can body.

This page gives you the exact numbers — height, diameter, circumference, volume, and caffeine — for every Red Bull size, in inches, centimeters, and millimeters. You’ll also find out why one size looks stretched and another looks stubby, how the can compares to everyday objects you already own, and whether it’ll clear the shelf in your mini-fridge.

The Number You Came For

The original Red Bull — the 8.4 fl oz (250 ml) slim can — stands 5.25 inches (13.3 cm) tall with a body diameter of 2.1 inches (53 mm). Wrap a tape around the middle and you get a circumference of about 6.5 inches (16.6 cm).

That’s the one most people mean by “a Red Bull.” Everything larger — 12 oz, 16 oz, 20 oz — keeps the same tall-and-lean personality but grows in both directions. The full breakdown is below.

Classic Can, Every Dimension

Here’s the complete spec for the 8.4 oz (250 ml) can across every unit, so you can grab whichever one your project needs.

Measurement	Inches	Centimeters	Millimeters	Feet
Height	5.25 in	13.3 cm	133 mm	0.44 ft
Body diameter	2.1 in	5.3 cm	53 mm	0.17 ft
Circumference	6.5 in	16.6 cm	166 mm	—
Radius	1.05 in	2.65 cm	26.5 mm	—
Volume	8.4 fl oz	250 ml	—	0.25 L

These figures match the can-maker’s published slim-can spec (roughly 133 mm tall by 53 mm across), so they’re about as close to official as you’ll get without a set of calipers. Expect real cans to wander by a millimeter or two — more on why in a moment.

The Full Red Bull Lineup, Size by Size

Red Bull doesn’t just scale one shape up and down. It borrows three different standard aluminum can bodies — slim (53 mm), sleek (58 mm), and standard (66 mm) — depending on how much liquid needs to fit. That’s the detail most size guides get tangled up in, and it’s why the diameters below don’t rise in a neat straight line.

8.4 oz (250 ml) — The Original Slim Can

This is the can that built the brand, launched in Austria in 1987 and rolled into the U.S. in 1997. It uses the slim 53 mm body — the narrowest format in mainstream energy drinks — which is exactly why it feels so different in the hand from a chunky soda can. Height lands at 5.25 in (13.3 cm), diameter at 2.1 in (53 mm).

Sugarfree, Zero, and the colored Red Bull Editions all ship in this identical shell, and they carry the same 80 mg of caffeine as the original — only the sweeteners and calories change, not the buzz. So if you’re measuring for a koozie, a display peg, or a fridge slot, treat every 250 ml flavor as the same object with the same dose.

12 oz (355 ml) — The Everyday Middle Size

Step up to 12 fluid ounces and Red Bull switches to the sleek 58 mm body. It stretches to roughly 6.1 in (15.6 cm) tall while staying only fractionally wider than the classic — about 2.3 in (58 mm) across. Hold one and it reads as a taller, more elegant version of the original rather than a bulkier one.

The volume jump is real: 355 ml is 105 ml more than the classic, matching the familiar U.S. 12 oz beverage standard, and it carries about 114 mg of caffeine. If you’ve ever wondered why it looks nothing like a squat 12 oz cola despite holding the same amount, that’s the sleek can at work — same liquid, taller and thinner package.

16 oz (473 ml) — The Tallboy

Here the can graduates to the standard 66 mm body, the same width used by most big energy drinks. It reaches about 6.9 in (17.5 cm) tall with a 2.6 in (66 mm) diameter — near-identical in stature to a 16 oz beer tallboy. This is the size built specifically to go head-to-head with the 16 oz cans that dominate American cooler shelves.

At 473 ml it holds precisely 16 U.S. fluid ounces, nearly double the classic, and roughly 151 mg of caffeine to match. The wider base makes it noticeably more planted on a desk, though it’s now too fat for the snuggest car cup holders that swallowed the slim can with room to spare.

20 oz (591 ml) — The Bigger Bull

The largest size in the U.S. range keeps the 66 mm body but pushes the height to roughly 7.6 in (19.3 cm). Some production runs read closer to 2.7–2.9 in across at the widest point, so call it 2.6–2.9 in (66–74 mm) to be safe. It’s the tallest can Americans will find on a normal shelf.

This is the strongest single-can option on U.S. shelves, packing about 189 mg of caffeine — more than two classic cans in one sitting. It’s also a two-hands-optional, sits-on-the-nightstand kind of can, genuinely tall enough to foul the top shelf of some compact fridges, so it’s worth a quick measure before you assume it’ll stand upright behind the door seal.

500 ml — Europe’s Tall Pour

Sold mainly across European and some Asian markets rather than U.S. stores, the 500 ml can uses the sleek 58 mm body stretched to around 7.9 in (20 cm) tall, holding about 160 mg of caffeine. It carries the extra volume through height, not width — so it’s about as tall as the 20 oz Bigger Bull but visibly slimmer.

Because it’s so tall, this is the format most likely to defeat a mini-bar fridge: many hotel-room coolers only offer 20–22 cm of shelf clearance, which leaves this can standing on tiptoe. Bottom shelf or door pocket is the safe bet.

Every Red Bull size at a glance. Diameters for the 12 oz and up are typical values — see the next section for why they flex.

Size	Volume	Height	Diameter	Can body	Caffeine
Classic	8.4 fl oz / 250 ml	5.25 in (13.3 cm)	2.1 in (53 mm)	Slim	80 mg
Medium	12 fl oz / 355 ml	6.1 in (15.6 cm)	2.3 in (58 mm)	Sleek	114 mg
Tallboy	16 fl oz / 473 ml	6.9 in (17.5 cm)	2.6 in (66 mm)	Standard	151 mg
Bigger Bull	20 fl oz / 591 ml	7.6 in (19.3 cm)	2.6–2.9 in (66–74 mm)	Standard	189 mg
Euro tall	16.9 fl oz / 500 ml	7.9 in (20 cm)	2.3 in (58 mm)	Sleek	160 mg

Caffeine, Scaled to the Can

Here’s the tidy part: Red Bull doses caffeine at a flat 32 mg per 100 ml, so the number tracks the volume exactly. That’s why the mg figures rise in step with the can size rather than jumping around like the diameters do.

• 8.4 oz (250 ml) — 80 mg, about the same as a small cup of drip coffee
• 12 oz (355 ml) — 114 mg
• 16 oz (473 ml) — 151 mg
• 20 oz (591 ml) — 189 mg, the strongest single U.S. can
• 500 ml (Europe) — 160 mg

Two things worth knowing. First, the caffeine is identical between regular, Sugarfree, and Zero — the diet versions swap the sweetener, not the stimulant. Second, per ounce Red Bull is fairly moderate; a 16 oz Red Bull and a 16 oz Monster land within a few mg of each other because both hover near that ~32 mg/100 ml mark. The classic can only feels small on caffeine because the can itself is small.

Caffeine figures are label-based; individual sensitivity varies, so this is general product information rather than dietary advice.

Why Two Rulers Give You Two Answers

Search five different pages and you’ll see the classic can listed anywhere from 4.75 to 5.3 inches tall and 2.08 to 2.25 inches wide. The cans aren’t inconsistent — the measuring is. A few honest reasons the numbers drift:

Where you put the tape. The narrow 53 mm figure is the body wall. Measure across the rolled seam at the top rim and you’ll pick up an extra couple of millimeters, which is how “2.25 in” sneaks into some charts. Both are “the diameter,” just of different circles on the same can.

With or without the lid dome. Height changes depending on whether you stop at the shoulder, the top of the domed lid, or the tip of the pull-tab. Most quoted heights include the lid but not the raised tab.

Manufacturing tolerance. Aluminum can walls are only about 0.1 mm thick, and forming lines run at blistering speed. A drift of ±1–2 mm in height and half a millimeter in diameter between batches and plants is completely normal.

Region and format. A “12 oz” can isn’t one fixed object — sleek and standard bodies both exist at that volume. That’s the biggest source of confusion in Red Bull size charts, and it’s why measuring the actual can in front of you always beats trusting a generic figure.

Picture It: What the Slim Can Sits Next To

Numbers are abstract, so here’s what the classic 250 ml can lines up against in real life. Estimates are flagged as such.

• A standard 12 oz soda can — the soda is shorter (about 4.8 in) but much fatter (2.6 in). Stand them side by side and the Red Bull looks like the soda can’s tall, skinny cousin.
• A modern smartphone — an iPhone-sized handset is about 5.8 in tall, so the can comes up a touch shorter than your phone standing on end.
• A highlighter or dry-erase marker — most run 5–5.5 in, right in the can’s height range. Roughly one marker equals one Red Bull, top to top.
• A billiard ball — a pool ball is about 2.25 in across; the can’s body (2.1 in) is a hair narrower. That’s a handy diameter gut-check.
• A golf ball — at 1.68 in, a golf ball is clearly slimmer than the can, so the can body is roughly a golf-ball-and-a-quarter wide.

Hold the can and it covers most of your palm lengthwise while your fingers wrap almost all the way around it — that easy one-handed grip is the whole point of the slim design.

Red Bull vs the Rest of the Cooler

Part of what makes the classic can feel small is the company it keeps. Most rival energy drinks skip the slim body entirely and go straight for the wide 66 mm can, which reads as short and stocky next to Red Bull’s original. Approximate figures for the popular sizes:

Drink	Volume	Height	Diameter
Red Bull (classic)	8.4 oz / 250 ml	5.25 in (13.3 cm)	2.1 in (53 mm)
Red Bull (tallboy)	16 oz / 473 ml	6.9 in (17.5 cm)	2.6 in (66 mm)
Monster Energy	16 oz / 473 ml	6.1 in (15.6 cm)	2.6 in (66 mm)
Rockstar	16 oz / 473 ml	6.1 in (15.5 cm)	2.6 in (66 mm)
Celsius	12 oz / 355 ml	6.1 in (15.5 cm)	2.3 in (58 mm)

The takeaway: at 53 mm, the original Red Bull has the slimmest body of any mainstream energy drink. Even Red Bull’s own tallboy, once it adopts the wide 66 mm body, is no narrower than a Monster — it just started life as the skinniest can on the shelf. 

Cup Holders, Fridges, and Shipping Cartons

If you’re measuring for a reason rather than trivia, the practical stuff:

Cup holders. The classic slim can (2.1 in) rattles happily in nearly every car cup holder, which typically fits up to about 3 in. The 16 oz and 20 oz cans (2.6 in and up) still fit standard holders but sit snug — worth knowing before a road trip.

Fridge and cooler slots. At 5.25 in tall the classic clears any door shelf. The 20 oz (7.6 in) and the European 500 ml (about 8 in) are the ones to watch — measure your shelf-to-shelf gap, because compact and mini-bar fridges often top out around 8 in of clearance.

Packing and shipping. A standard 24-can tray of classic cans is built on that 53 mm footprint, so cans nest tightly. If you’re boxing them yourself, plan around a ~55 mm cell width per can to leave room for the seam, and remember a full 250 ml can weighs roughly 300 g (about 10.5 oz) once you add the aluminum to the liquid.

Koozies and sleeves. Grab a “slim can” koozie for the 250 ml, not a regular one — a standard soda koozie sized for 66 mm cans will slide right off the narrow body.

Quick-Fire Q&A

How tall is a 250ml can of Red Bull?

A 250 ml Red Bull stands 5.25 inches (13.3 cm / 133 mm) tall, measured to the top of the lid. That makes it taller than a regular soda can but much slimmer.

What is the diameter of a 12oz Red Bull can?

The 12 oz (355 ml) can is about 2.3 inches (58 mm) across the body — the “sleek” can format. It’s wider than the classic slim can but narrower than a standard soda can.

What is the size of a regular Red Bull can?

A regular Red Bull is the 8.4 oz (250 ml) slim can: 5.25 in (13.3 cm) tall, 2.1 in (53 mm) wide, with a 6.5 in (16.6 cm) circumference. It holds 250 ml and carries 80 mg of caffeine.

What is the size of a 250ml Red Bull can?

The 250 ml can measures 5.25 in (13.3 cm) tall by 2.1 in (53 mm) in diameter, holding 8.4 fluid ounces. It’s the original slim format sold worldwide.

Is 1 Red Bull a day unhealthy?

One 250 ml can (80 mg caffeine, ~27 g sugar) sits well within the ~400 mg daily caffeine limit healthy adults are generally considered able to tolerate. The bigger concern for most people is the sugar, so Sugarfree is the lighter daily choice — this is general info, not medical advice.

Locking the Size Into Memory

If you remember one thing, make it this: a regular Red Bull is a 5.25-inch, 2.1-inch-wide slim can — taller than a soda, skinnier than everything around it. Every bigger size keeps that lean look but climbs the ladder of can bodies, from slim to sleek to standard, which is the real reason the diameters jump around. Measure the actual can in your hand for anything mission-critical, and you’ll never be off by more than a millimeter or two.
