Decluttering Your Life: Why the “One In, Two Out” Rule is a Game Changer
Facing a significant life change, like an upcoming house move in 2026, can be a powerful catalyst for re-evaluating our relationship with possessions. For many, myself included, the instinct might be to acquire more, especially during tempting shopping seasons. However, with a large-scale transition on the horizon, the prevailing sentiment shifted from accumulation to reduction. The challenge then became how to curb the urge to shop without completely abstaining, leading to the adoption of a modified decluttering strategy: the “One In, Two Out” rule.
This approach offers a low-effort, yet highly effective, method for significantly downsizing your belongings without dedicating endless hours to the sorting and discarding process. It’s a surprisingly simple concept that yields substantial results, transforming not just your living space but also your purchasing habits.
Understanding the “One In, Two Out” Method
At its core, the “One In, Two Out” method is an extension of the well-known “One In, One Out” rule. The principle is straightforward: for every single new item that enters your home, you must remove two existing items. This simple equation ensures that your overall volume of possessions steadily decreases over time.
This technique was first put into practice as a targeted solution to a specific hoarding habit – shoes. Faced with an overwhelming collection of footwear, and a desire to organize it more effectively, the “One In, Two Out” rule proved remarkably easier to implement than anticipated. The immediate goal was to purchase a new pair of shoes, and the accompanying task of parting with old, worn-out pairs became a natural consequence. Shoes that were still in decent condition were donated to charity, while those beyond repair were discarded.
The results were more impactful than expected. In that initial shoe decluttering spree, six pairs were removed, and with the subsequent purchase of just two new pairs, the rule was not only met but exceeded, with three items being removed for each new acquisition. The newly organized shoe collection was then neatly stored in stackable plastic bins, tucked away for easy access.
Since then, this principle has become a subconscious filter for all shopping decisions. It’s become a passive decluttering strategy that continually refines storage solutions and, most notably, keeps the closet in check. Given that clothing is the category most frequently purchased, this rule has been particularly instrumental in managing its volume.
Beyond Physical Space: A Shift in Mindset
Interestingly, the benefits of the “One In, Two Out” rule extend far beyond simply clearing out closet space without making new purchases. It has fundamentally altered the approach to shopping itself. Now, before any purchase is considered, there’s an immediate mental inventory of what items could be removed to make way for the new one. If a suitable replacement isn’t readily apparent, it prompts a deeper consideration of whether the purchase is truly necessary or worth making.
While this strategy initially focused on clothing and shoes, its influence has rippled into other areas of life. The only exception, admittedly, are books. Following a year-long book-buying ban that concluded at the end of 2025, a deep appreciation for literature has led to a reluctance to part with them. However, combined with a makeup buying ban implemented in 2025, the overarching goal of combating overconsumption is being addressed from multiple angles well into the new year.
Tracy McCubbin, CEO and founder of dClutterfly, highlights the psychological impact of this method. She explains, “If you force yourself to get rid of two things for every one thing that you purchase, you are giving yourself a bigger task to complete. You are essentially taking away the dopamine hit that the purchase gives you, which may lead you to not want to purchase the item anymore at all.” This observation resonates strongly, as the act of decluttering two items diminishes the immediate gratification of acquiring one.
McCubbin further elaborates, “You’re also de-incentivizing shopping, knowing that you have to let go of more than you are bringing in. By getting rid of two things for every one thing that you bring in, you are always decluttering more than you are acquiring. A little decluttering at a time adds up to a big change before you know it!” This cumulative effect is precisely what makes the “One In, Two Out” rule so powerful for long-term change.
Ben Soreff, a professional organizer at House2Home Organizing, echoes this sentiment, stating that the “One In, Two Out” method serves as an excellent philosophy for anyone aiming to reduce volume and clutter. He advises, “When it comes to accumulating items, focus on quality and ask why you are buying it. Many people enjoy retail therapy, and that can lead to collecting instead of purchasing items for actual use.” This emphasis on intentionality and purpose is crucial for sustainable decluttering.
Why “One In, Two Out” Outshines “One In, One Out”
While the “One In, One Out” rule is undoubtedly beneficial for fostering conscious purchasing habits and encouraging self-reflection before buying, the “One In, Two Out” rule offers a more potent solution for those seeking to actively declutter and create a tangible difference in their living space.
Tracy McCubbin clarifies this distinction: “By getting rid of two items for every new item in, you are actively decluttering and will ultimately end up with less than you started with. This keeps you focused on what you really need and use. With one in, one out, you are just staying with the status quo.” The key difference lies in the net outcome: “One In, One Out” maintains the current level of possessions, whereas “One In, Two Out” guarantees a reduction.
