What Size Industrial Shed Does Your Business Need?

There’s a lot riding on getting the size right when you browse the industrial shed range and start planning. Guess wrong on industrial shed sizes and you’re either squeezing forklifts past storage racks within a year, or paying for empty floor space every month.

If you’re asking what size industrial shed you need, the honest answer is: it depends on what you’re doing inside it, not on a single standard number that suits every business. This industrial shed size guide walks through the questions that actually matter, so you land on the right footprint the first time.

Why the Right Size Actually Matters

Sizing an industrial shed isn’t just about fitting everything in on day one. It’s about avoiding two expensive outcomes: paying to run and maintain space you don’t use, or paying again in a year or two to extend a shed that’s already too small.

The right size also affects how your business actually operates day to day. A cramped layout slows staff down, makes moving equipment awkward, and turns simple tasks like loading a truck into a longer job than it needs to be. Getting it right from the start protects both your budget and your day-to-day efficiency.

Start With Your Use Case

Different businesses need different things from the same square metreage. Best Sheds’ industrial range runs from 12x12m through to 18x36m, and Best Sheds can customise to any size you need if your operation calls for something outside that range.

Mechanic Workshops

These typically need enough width for two to three service bays, plus a dedicated tools and parts area and somewhere for customers to wait, with extra width if you’re running hoists side by side rather than in a single line.

Fabrication Businesses

These need extra length more than extra width. Welding bays, cutting stations, and raw material racking all eat into floor space fast, and dust extraction equipment needs its own footprint too.

Warehousing

This is usually about maximising floor space and racking height rather than width. Pallet racking works best with long, uninterrupted runs and clear aisle widths for forklift access, so a longer, taller shed tends to suit better than a squarer footprint.

Landscaping Depots

These need room for machinery, trailers, and bulk materials like mulch, soil, or aggregate stored side by side. Vehicles also need to manoeuvre between bays without unloading everything first, which often calls for a wider footprint rather than a long, narrow shape.

Running a large industrial shed operation across multiple product lines? Err on the larger side. It’s far cheaper to engineer the right size once than to extend later, and commercial shed sizes in Australia rarely shrink to fit a business that’s grown. If your requirements don’t fit neatly into a standard range, custom shed design lets you specify your own dimensions instead of compromising.

Common Sizing Mistakes to Avoid

A few mistakes come up again and again when businesses size an industrial shed, and most of them are easy to avoid once you know to look for them.

Undersizing the Door, Not the Shed

A shed can be plenty big inside and still cause problems every day if the roller door is too narrow or too low for what needs to drive through it.

Forgetting Growth

Businesses that size a shed for exactly what they need today often outgrow it within a couple of years. If you’re planning to add a second vehicle, more racking, or an extra staff member down the track, size for that now rather than extending later.

Ignoring Turning and Manoeuvring Room

A shed that’s the right floor area but too narrow to turn a truck or forklift around in becomes frustrating fast, even if every square metre is technically accounted for.

Treating Height as an Afterthought

Wall height gets overlooked more than floor space, but it’s just as easy to get wrong, especially once racking or taller equipment come into the picture.

Staff Numbers and Equipment Footprint

Before you settle on a size, walk through a normal working day. How many staff are on site at once, and how much room does each of them need to move safely around machinery, benches, or racking?

Measure your biggest pieces of equipment, including any attachments or extensions, and add clearance on every side. A shed that’s technically big enough on paper can feel cramped the moment two people are working near the same machine, or when a forklift needs to pass behind someone at a bench.

It’s also worth thinking about non-obvious space needs: a lunchroom or amenities area, an office corner, or a designated spot for waste and recycling. These don’t need much room individually, but they add up, and they’re easy to forget until the shed is already in place.

Vehicle Access

If trucks, forklifts, or trailers need to get in and out, plan for that before you plan for anything else. A roller door that’s too narrow or too low turns a good shed into a daily bottleneck, no matter how much floor space is behind it.

Think about turning radius as well as door width. You need enough room to reverse a truck in, not just drive it through in a straight line, and enough clearance to do it without a ten-point manoeuvre every time.

If more than one vehicle needs access at once, consider whether a single large door or multiple smaller doors suits your workflow better. A single wide door works well for occasional large deliveries, while multiple doors can keep day-to-day traffic moving without vehicles queuing behind each other.

Height for Racking and Forklifts

Wall height matters as much as floor space, especially once tall racking or a forklift are part of daily operations. Best Sheds’ industrial range goes up to 5m in height, giving plenty of room for high-reach racking without feeling cramped.

A forklift with a raised load needs more vertical clearance than most people expect, particularly once you account for the mast fully extended rather than at rest. If your operation includes high-reach racking, this is often where a shed that looked tall enough on paper turns out to be tight in practice.

If you’re unsure how much height you’ll need, plan for slightly more than your current equipment requires. Upgrading a forklift or installing taller racking later is far easier when the shed was engineered with room to spare from day one.

A Quick Way to Check Your Thinking

If you’re still narrowing things down, a simple gut check helps: picture your busiest possible day in the shed, with every staff member, vehicle, and piece of equipment in use at once. If that scenario feels comfortable in the size you’re considering, you’re probably on the right track. If it feels tight even in your head, it’s worth sizing up.

Get the Size Right the First Time

Sizing an industrial shed properly means matching the structure to how you’ll actually use it, not just picking a number that sounds about right.
