Sorting laundry properly takes two or three extra minutes and saves a lot of ruined clothes. Pink socks, grey whites, and shrunken wool jumpers are almost always the result of skipping this step.
But sorting doesn't have to happen as a separate chore before every wash. The goal is to set up your baskets so that sorting happens automatically as you put clothes in, so by the time laundry day arrives, the hard work is already done.
Why Sorting Matters
There are three main reasons to sort:
• Colour bleeding: dark or bright dyes, especially from new items, can transfer onto lighter fabrics in a warm wash. Once a white shirt turns pink, it's very difficult to reverse.
• Fabric care differences: delicates like silk, wool, and lace need a gentle cycle at lower temperatures. Heavy items like jeans, towels, and bedding can withstand a hotter, longer wash. Mixing the two means something gets the wrong treatment.
• Abrasion: heavy items like denim and towels can cause physical wear on more delicate fabrics in the same load, even on a cold, gentle cycle.
Step 1: Sort by Colour
The standard approach is a three-way colour split:
• Whites and very light colours (white, cream, pale yellow, light grey)
• Darks (black, navy, dark grey, dark green, dark brown)
• Brights (bold reds, oranges, yellows, bright blues and greens, colours that can bleed onto each other as well as onto lighter fabrics)
According to Better Homes & Gardens, "new dark-coloured clothes may continue to bleed dye for the first several washes," which is why washing new items separately or with very similar colours is recommended. (Source: Better Homes & Gardens)
If your wardrobe doesn't have a lot of brights, a simpler two-way split (lights and darks) works fine for most households.
Step 2: Sort by Fabric Type
Once you've got the colour sort handled, add a second layer based on how items need to be washed:
• Delicates: silk, wool, lace, lingerie, fine knitwear, these need a gentle or hand-wash cycle and low temperatures. Using a mesh laundry bag gives extra protection.
• Everyday cottons and synthetics: t-shirts, underwear, casual trousers, activewear, these are the bulk of most loads and handle a standard cycle well.
• Heavy items: towels, jeans, bedding, hoodies, these suit a longer, warmer cycle and are best kept separate from delicates to avoid abrasion.
The care label is your guide. For blended fabrics (e.g. 60% cotton, 40% polyester), follow the care instructions for the dominant fibre.
Building Your Multi-Basket System
The simplest way to make sorting automatic is to give each category its own basket. Here's how to scale the system to your household:
Single Person or Apartment Dweller
Two baskets usually cover it: one for lights/whites and one for darks. A third small mesh bag or container for delicates is a low-cost addition if needed. Do laundry frequently enough, and you won't need a large capacity; two medium baskets (~45L each) work well.
Couple or Small Family
Three baskets or a divided laundry sorter: whites, darks, and either delicates or brights, depending on what your wardrobe generates most. A divided sorter is a compact all-in-one option if floor space is tight.
Larger Family
Multiple baskets, including one dedicated to towels and heavy items (which fill up fast with kids in the house), plus the standard colour split. Some families find it easier to give each family member their own labelled basket, with a shared hamper for towels and bedding.
Our laundry basket range includes options in multiple colours and sizes, making it easy to colour-code your baskets so every household member knows exactly where things go.
Labelling and Household Buy-In
A system only works if everyone uses it. Labelled or colour-coded baskets remove the need to think, the decision of where to put something is already made. Options include:
• Sticky labels or chalkboard labels on each basket
• Different coloured baskets for different categories (one white basket for whites, one dark basket for darks)
• A short explanation stuck to the laundry cupboard door for anyone new to the system
Removable labels are useful since your laundry needs can shift, in summer, you might add an extra dedicated basket for swimwear or activewear.
Special Cases Worth Knowing
Heavily Soiled or Very Sweaty Items
Gym kit, heavily soiled work clothes, or muddy sportswear are worth keeping in a separate small basket. Odours and grime can transfer to the rest of the laundry if left sitting together for days, especially in a warm bathroom or laundry room.
Delicates in Mesh Bags
If you're sorting delicates into a main colour load (rather than washing them separately), putting them in a mesh laundry bag first provides extra protection against abrasion without needing a dedicated wash cycle.
Clean vs Dirty: A Common Mistake
It seems obvious, but it's worth flagging: don't put folded clean laundry back into the same basket that just held dirty clothes. The basket absorbs smells and bacteria over time, and clean items pick this up quickly.
The simplest fix is a clearly different basket for clean, folded laundry — a different colour or material works well. This also links into keeping your baskets clean and odour-free, which we cover in our guide to keeping your laundry basket fresh and mould-free.
You can also explore smart organisation ideas in our guide to small-space laundry organisation, which covers how to fit a multi-basket system into an apartment, small bathroom or shared housing.
Summary: Your Sorting System in Three Steps
• Sort by colour first: whites/lights, darks, brights, or a simple two-way split if your wardrobe is straightforward.
• Add a fabric-type layer: keep delicates separate, and consider a dedicated pile for heavy items like towels and bedding.
• Assign a basket to each category and label them, so sorting happens automatically as clothes come off, not as a separate chore before the wash.
Once your system is running, the next thing to focus on is keeping those baskets themselves clean and fresh, which is exactly what the next guide covers.
