Before you take the plunge and buy that washing machine you've been eyeing, have you thought about what size washing machine you need? From the number of loads you run per week to the size of your household, here's an easy guide to follow so you can get the right appliance the first time.

What is the standard size of a washing machine?

When you’re ready to buy a new washing machine, the first thing you need to think about is which size you’re looking for. Size is based on the washing machine’s capacity, or the maximum amount of laundry that a washing machine can efficiently clean in one load. For most washing machines, the height and width measurements stay the same while depth will change based on capacity. But for some extra-large washing machines with over 13 kg of capacity, all three measurements will change, so you’ll need to check whether you have enough space for installation. Measured in kilograms, this capacity usually ranges from 6-18 kg and is always measured in terms of dry clothes, never wet. The capacity you need is based on how much laundry you run per load — is it a few t-shirts, or a king-sized duvet? Finding the right capacity is important, but if you’re stuck between two sizes, it’s better to go with the higher capacity. Why? Because if you overload your washing machine, it could be too full to actually clean your clothes, as the laundry and detergent wouldn’t have room to move. Or worse, you could damage the machine due to the difference in weight once your laundry is wet. Let’s take a look at the different sizes.

Small washing machines

Small washing machines (or slimline washing machines) generally start from 6 kg washing machines, but also include 7 kg washing machines. Up to 480 mm in depth, you can easily place them in smaller, tighter spaces, so they’re great if you live in an apartment or condo. These slim washing machines fit 9-10 bath towels in each load1 — perfect for one or two-member households. Save up your laundry for the week and pop it in without worrying about needing to do multiple loads.

Medium-sized washing machines

Medium-sized washing machines usually include 8 kg washing machines, 9 kg washing machines and 10 kg washing machines, and measure between 550-600 mm in depth. If you have a family of two or three, this capacity can handle your weekly laundry, while also fitting in some bigger items like duvets. You can run a load of up to 11-14 bath towels1. From children to who love to play outside to finding food stains on your clothes from dinner, these washing machines keep up with your family’s lifestyle.

Large washing machines

Large washing machines include 11 kg washing machines and 12 kg washing machines at a depth of 600-650 mm, and are designed for families of four or more. There are even some extra-large washing machines with over 13 kg of capacity, which aren’t suitable for undercounter installation as it exceeds standard width and height — so be sure to check dimensions and space requirements before buying. As the largest sizes available, these washing machines fit large loads with ease, from everyone’s weekly laundry to your favorite comforter, so there’s less to fuss over during the week when life is already so busy. Run your loads with 16-17 bath towels1, because now it’s even easier to keep up with your day-to-day.

How do I measure for a new washing machine?

Unsure where to start? Don’t worry, there are just a few things you need to do to make sure you have the right size washing machine for your space.

Find the width, depth and height

Most washing machines have standard dimensions for width and height, so focus on getting the right washing machine depth measurements as these can vary widely by manufacturer, model and capacity.

Undercounter installation

Whether a standard-sized washing machine or a tiny washer-dryer combo, if you choose undercounter installation you want at least 25 mm of clearance on both sides, as well as at least 50 mm of space at the back for the hoses and any ventilation.

Stacked installation

With a stackable washer and dryer, keep a close eye on the measurements. Make sure there’s at least 25 mm of space surrounding the top and sides, 50 mm of rear space and 550 mm for the washing machine and dryer doors. And don’t forget to factor in ceiling height, or your ability to reach the controls!

Side-by-side installation

Thinking about placing a large washer and dryer side by side? Take note of the width measurements. You will want to have enough room, at least 550 mm, to fully open the doors. Plus, there should also be a 25 mm gap between the walls, as well as in-between and above the appliances.

Washer-dryer combo for smaller spaces

Live in a smaller home, apartment or condo? Then a washer-dryer combo is a great way to make the most of your space. Rather than having a separate washing machine and tumble dryer taking up twice the space, you can have two appliances in one — which also helps you save on time.

How should you install your washer and dryer?

Whether stacked or side by side, the perfect installation is all about you and your space.

Stacked installation

Stacking your tumble dryer on top of your washing machine is a great option for those with a small, stackable washing machine and dryer and high ceilings. When installing, double check that the two are level and secure in place and you've placed the dryer on top of the washer. Even slimline washing machines are heavy when they’re filled with water!

Side-by-side installation

For those with enough space, having your perfect-sized washing machine and tumble dryer installed side by side allows for easy loading and unloading — important when you have to do multiple loads a week! Simply pop a tumble dryer next to your washer and enjoy.
