If you’ve been around the world of decluttering for a while, you’ve probably heard of the “one in, one out” rule.
If not, the idea is simple: every time you bring something new into your home, you let go of something else.
- Buy a new sweater? Donate an old one.
- Bring home a new mug? Out goes one from the cupboard.
It makes sense, and I understand why people embrace it.
And yet … I don’t love it.
Because while the “one in, one out” rule sounds like a great way to stay clutter-free, in practice, it can quietly keep you stuck in the same cycle you’re trying to escape. Let’s take a look at why this happens, and what I recommend trying instead.
The Conveyor Belt Problem
I followed this rule for years, especially when it came to my wardrobe. On paper, it worked — my closet never overflowed, and everything had its place.
But over time, I noticed something strange. Despite keeping my wardrobe under control, I was still shopping more than I should. I’d declutter clothes that didn’t quite fit or didn’t feel right, then go out and buy more of the same.
My closet had become a conveyor belt: things in, things out, nothing changed.
The “one in, one out” rule helped me manage clutter, but it didn’t help me stop creating it.
And that’s the real problem. It keeps your home looking tidy, but it doesn’t solve the deeper issues: overconsumption, wasted money, decision fatigue, and the emotional clutter that comes with constantly chasing something better.
What I Want More Than Less Stuff
At its core, decluttering isn’t just about keeping the numbers down. Instead, it’s about alignment: how can we create homes and lives that reflect our values and priorities?
For me, some things that matter include:
- Reducing environmental waste (and the best way to do this is to buy less in the first place).
- Saving money (and again – buying less is the best place to start!)
- Being more intentional with my time and energy (which means investing less into buying and getting rid of things)
None of this was happening when I was cycling through clothes—and, to some extent, the “one in, one out” rule was actually enabling me to make poor choices. It was like a minimalist loophole that let me keep shopping without guilt.
What’s Missing: Reflection
After realising my actions weren’t aligned with my goals, I decided to make a few changes.
First, I started paying attention to what I was decluttering and why. For example, before decluttering a sweater, I might ask myself:
- Why didn’t that sweater work for me?
- What was I hoping this new purchase would fix?
- What patterns am I repeating?
The awareness I gained from these small moments of self-reflection was monumental. I realised that I’m actually very picky about fabrics (synthetics just don’t work in a subtropical climate) and that there are many styles I like more on other people than I do on myself.
This information completely changed what I keep and buy, which in turn changed the flow of items in and out of my house. The things I purchased were better suited to my life, and the “conveyor belt” naturally slowed.
Still, I missed the structure of the “one in, one out” rule, so I replaced it with something better.

Instead Of “One In, One Out,” Set Boundaries
Traditionally, boundaries are a way of preserving our time and energy. We get to know ourselves, and then set rules that help us maintain our sanity peace of mind.
For example, if staying out late on Sunday nights makes you feel stressed and unprepared for the week, you might set a boundary where you’re always home by five.
This removes decision fatigue and makes it easy to follow through with what you know is best. When you get an invitation for a night out, you don’t have to overthink things or make excuses. Instead, you simply state your boundary – politely yet firmly.
And guess what?
We can do the same with our clutter.
I know that when I have too many clothes, it feels overwhelming and, ironically, it’s harder to get dressed. So I set boundaries for my closet.
Take my sweaters, for example. Because I live in a warm climate (and live in a tiny apartment with two kids!), I know I don’t need a lot, so I limit myself to one small basket.
(The size doesn’t matter; the point is that you choose a realistic limit based on your lifestyle.)
This boundary is powerful because it’s my way of defining how much is enough – and this stops the clutter cycle.
Of course, this doesn’t mean that I never replace things! But when I do, it’s intentional. I have clarity about what I wear, what I use, and what I need, and it’s no longer a cycle of one thing in, one thing out.
This method was so successful that I actually did a 14-month shopping ban a few years ago. I realised I had enough, and I simply stopped buying more.
The Bigger Picture
Now, to be clear, I’m not saying the “one in, one out” rule is bad. For some people, it’s a helpful maintenance strategy, especially once you’ve decluttered and found your definition of “enough.”
But if you struggle with over-shopping, decision fatigue, or feeling like clutter keeps creeping back, it might not be the right fit.
Because decluttering isn’t just about getting rid of stuff; You want to create new habits, and break the cycle altogether. The rule dealt with the symptoms, but it didn’t inspire any lasting change.
So next time you find yourself tempted to buy something new, don’t just ask, “What will I get rid of?”
Instead, try “Why do I feel like I need this — and what would change if I decided I already have enough?”
That’s where clutter-free living truly begins.
