The 90/90 rule for decluttering your bedroom

Some decluttering methods ask how you feel about your stuff. The 90/90 rule doesn’t care about feelings. It just asks one question: when did you last use this?

Created by The Minimalists (Joshua Fields Millburn and Ryan Nicodemus), the 90/90 rule works like a deadline for your belongings. Pick up any item in your bedroom and ask two questions: Have I used this in the last 90 days? Will I use it in the next 90? If the answer to both is no, it goes. No agonising, no “but what if,” no putting it back on the shelf for another six months.

It’s blunt. That’s the point.

How to use it in the bedroom

The easiest way to apply the 90/90 rule is to work through your bedroom in zones rather than tackling it all at once.

The wardrobe is usually the biggest win. Pull everything out and go through it item by item. That shirt you bought for a wedding in 2023? Hasn’t been worn since. The jeans you’re keeping because they might fit again? Not in the last six months. The 90/90 rule takes the guesswork out of these decisions.

Surfaces and drawers are next. The bedside table is a magnet for things that don’t belong anywhere: old chargers, random receipts, skincare samples from three hotels ago. Apply the same 90-day filter, and most of it goes straight into the bin or the charity bag.

Under the bed is the last zone and usually the most revealing. If you haven’t looked under there in 90 days, there’s a good chance you’ve forgotten what’s down there. That tells you everything you need to know.

The seasonal exception

The one caveat is seasonal items. Your thick winter duvet doesn’t need to pass the 90-day test in July, and your summer bedding doesn’t need to justify itself in December. Use common sense with anything that has a clear seasonal purpose.

The trick is making sure seasonal items have a proper home rather than living in a pile at the back of the wardrobe. An ottoman bed is brilliant for this. The full-length storage underneath is deep enough for duvets, blankets and out-of-season clothes, and everything stays out of sight until you need it. Our ottoman beds guide explains the different styles if you’re weighing up options.

The 90/90 rule vs other decluttering methods

A lot of decluttering methods rely on how things make you feel. That’s fine in theory, but feelings are complicated. You might feel guilty about a gift, or nostalgic about a hoodie you never wear, or convinced you’ll need something “one day.”

The 90/90 rule cuts through all of that with a simple yes or no. Either you’ve used it recently and will again, or you haven’t and you won’t. It’s surprisingly freeing once you commit to it.

Why does it suit bedrooms so well?

Bedrooms are full of things we keep out of habit. The spare pillows stacked on the chair. The candle that’s been on the windowsill, unlit, for months. The pile of clothes that have been “tried on and rejected” so many times they’ve become part of the furniture. The 90/90 rule cuts through that autopilot clutter because it doesn’t let you rationalise. It just asks: when?

The 90/90 rule is one of eight approaches in our full guide to decluttering methods for busy bedrooms. If you need a clear line in the sand to make decisions, this one’s for you. And if you want something gentler, there are plenty of other options on the list.
