If you’ve ever stood in front of a closet full of stuff you don’t use and still couldn’t bring yourself to throw anything away, you’re not alone. Decluttering is one of those tasks that sounds simple until you’re actually doing it, and suddenly every item has a reason to stay. The 90/90 rule is a straightforward framework that cuts through all of that, and it’s particularly powerful if you’re getting ready to sell your home.
Here’s how it works and how to put it to use.
What Is the 90/90 Rule?
Originally developed by the authors behind The Minimalists, the 90/90 rule replaces the endless “but what if I need this someday?” spiral with just two honest questions:
• Have I used this in the past 90 days?
• Will I realistically use it in the next 90 days?
If the answer to both is no, it’s probably just taking up space. That’s it. No complicated scoring system, no emotional negotiation, just two questions and an honest answer.
The beauty of this approach is that it shifts the conversation from hypothetical future use to actual real-life habits. Most of us hold onto things based on who we think we are or what we think we might do someday. The 90/90 rule brings it back to reality.
When the Rule Doesn’t Apply
The 90/90 rule isn’t meant to be rigid. Seasonal items, winter coats, holiday decorations, luggage, naturally fall outside a three-month window and shouldn’t be tossed just because they haven’t been touched lately. The point isn’t to strip your home down to nothing. It’s to question whether each item genuinely serves a purpose in your daily life versus just occupying space out of habit or guilt.
Where to Start
The rule works in virtually any room, but a few areas tend to yield the biggest results:
• Closets and wardrobes. If you haven’t worn it in three months and can’t picture wearing it in the next three, it’s probably not coming back into rotation. Donate it and reclaim the space.
• Kitchen cabinets and drawers. Single-use gadgets, novelty mugs, and specialty appliances are classic space hogs. If it hasn’t earned a spot in your regular routine, it doesn’t need a cabinet.
• Bathroom storage. Expired products, duplicates, and half-used toiletries accumulate fast. The 90/90 rule helps you curate down to what you actually use every day.
• Storage areas. This is where the rule gets really revealing. Many stored items haven’t been touched in years, and applying the two questions honestly can free up significant space.
Why This Matters If You’re Selling
A decluttered home photographs better, shows better, and sells faster. Buyers need to be able to visualize themselves in your space, and that’s nearly impossible when every shelf and closet is packed. Getting ahead of the clutter before you list isn’t just about aesthetics. It reduces the stress of moving, makes staging easier, and can genuinely impact your sale price.
Start room by room, ask the two questions honestly, and let the answers guide you. Small, consistent progress adds up faster than you’d expect.
