Know the Different Brick Dimensions (Because Size Actually Matters)

Hey there, fellow brick enthusiasts! Let’s cut to the chase: if you’ve ever stared at a wall or a patio and thought, “Huh, why do these bricks look… off?”—chances are, it’s all about the dimensions. Yeah, we know, it sounds like the least exciting part of a project. But trust us, getting brick dimensions wrong is like wearing mismatched socks to a job interview. It might seem trivial, but someone will notice.

Here at The Brick Pit in Australia, we’ve seen it all—DIYers accidentally building lopsided fireplaces, pros scratching their heads over reclaimed bricks that just won’t line up. That’s why we’re breaking down everything you need to know about brick sizes. And hey, if you’re feeling overwhelmed, just give us a shout. We live for this stuff.

Why Brick Dimensions Aren’t Just “Size Talk”

Let’s get real: bricks aren’t one-size-fits-all. Think of them like jeans—there’s a fit for every purpose, and nobody wants a pair that’s too tight in the wrong places. Whether you’re working with recycled bricks for a rustic vibe or sleek sandstock bricks for a modern build, dimensions dictate everything: structural integrity, aesthetic flow, and even how much coffee you’ll need to fix a mistake.

FYI, Australia’s standards differ slightly from other regions, which is why partnering with a local supplier (hi, it’s us!) saves headaches. For instance, second hand bricks often come with “character” (read: irregular sizing), so knowing their specs upfront is critical.


The ABCs of Brick Sizes: A Quick Cheat Sheet

Brick dimensions are usually listed as Length x Width x Height. But here’s the kicker: nominal vs. actual sizes can trip you up. Nominal includes mortar joints; actual is the brick’s raw measurement. Confused? Let’s simplify:

Common Australian Brick Dimensions

  • Standard (Modular): 230mm x 110mm x 76mm
  • Standard (Non-Modular): 290mm x 110mm x 76mm
  • Jumbo: 305mm x 153mm x 162mm

Pro tip: Reclaimed bricks might vary—we’ve seen vintage gems as small as 200mm long. Always measure twice, order once.


When Old Meets New: The Quirks of Recycled & Second Hand Bricks

Raise your hand if you’ve ever fallen in love with a pallet of recycled bricks, only to realize they’re all slightly different sizes. Yeah, us too. Older bricks—think pre-1970s—were often handmade, leading to charming inconsistencies. But unless you’re aiming for a “cottagecore chaos” aesthetic, here’s what to do:

  1. Sort by size before building.
  2. Mix and match strategically (smaller bricks for detailing, larger ones for structural sections).
  3. Buy 10% extra to account for quirks.

At The Brick Pit, we grade our second hand bricks by era and size, so you’re not playing Guess Who? with your materials.


Sandstock Bricks: The Unsung Heroes of Texture

Sandstock bricks are like the artisanal sourdough of the brick world—rough-textured, durable, and full of personality. Their dimensions? Usually standard (230mm x 110mm x 76mm), but their uneven edges mean mortar joints can vary. IMO, they’re perfect for feature walls where imperfection is the whole point.

Word to the wise: If you’re pairing sandstock with reclaimed bricks, check their heights. Nothing kills a vibe faster than a row that’s taller than your toddler.


The Mortar Matrix: How Dimensions Affect Your Build

Ever wondered why bricklayers seem so obsessed with spacing? Let’s do math (don’t panic—it’s simple). If your brick is 230mm long and you add a 10mm mortar joint, each course (horizontal layer) effectively becomes 240mm. Screw this up, and your wall might end up looking like a lopsided pizza.

Pro hack: Use a spacer tool. Even better, let The Brick Pit help you source bricks with uniform dimensions. We’ll save you from mortar-induced meltdowns.


Brick Dimensions Comparison Table

Brick Type Length (mm) Width (mm) Height (mm) Common Uses
Standard Modular 230 110 76 Walls, pavers
Non-Modular 290 110 76 Structural projects
Jumbo 305 153 162 Commercial builds
Recycled (Vintage) 200–240 90–120 70–80 Feature walls, gardens

“But Why Does This Even Matter?” (And Other FAQs)

Q: Can I mix brick sizes in one project?
A: Absolutely—if you’re a fan of puzzles. For the rest of us, stick to one size unless you’re deliberately creating a patchwork design. Reclaimed bricks work great here, but plan ahead!

Q: Are bigger bricks cheaper?
A: Sometimes, but labor costs can offset savings. Jumbo bricks cover more area, but they’re heavier and trickier to handle.

Q: How do I match old bricks for repairs?
A: Bring a sample to The Brick Pit. We’ll find a second hand brick doppelgänger or recommend a modern alternative.
