Use the 90/90 Rule to Declutter Sentimental Stuff

What is the 90 90 rule to declutter sentimental items?

The 90/90 rule is a simple decision filter: if you haven’t used an item in the last 90 days and you don’t expect to use it in the next 90 days, it’s a candidate to let go. When you apply it to sentimental items, the goal isn’t to dismiss the memory—it’s to separate the memory from the physical object so your space reflects what truly matters.

How the 90/90 rule works for sentimental clutter

Sentimental belongings often don’t have a “use” in the everyday sense, so reinterpret the rule as “meaningful engagement.” Ask: Have I looked at this, displayed it, or shared its story in the last 90 days? Will I realistically do that in the next 90? If the answer is no, the item may be more about guilt or obligation than genuine value.

When the rule is especially helpful

The 90/90 rule shines with duplicates and “maybe someday” keepsakes—old greeting cards, event programs, childhood papers, and inherited knickknacks you never chose. It also reduces decision fatigue because it gives a consistent threshold, rather than relying on a wave of emotions in the moment.

How to keep the memory without keeping everything

If something fails the 90/90 test but still tugs at you, choose a memory-preserving alternative: take a clear photo, write a short note about why it mattered, or keep only the best representative piece from a category (like one concert ticket, not a full stack). Consider a small “favorites” box with a firm size limit—once it’s full, something must leave before anything new enters.

Exceptions you can plan for

Some items are seasonal (holiday décor), milestone-based (wedding album), or legally important (documents). Create a separate category for “planned-use” items so the rule stays fair and you don’t second-guess essentials.

FAQ

How do you decide what sentimental items to keep?

Keep items you intentionally revisit, display, or would genuinely miss, and let go of the ones kept from guilt or “just in case.” Choosing one best example from a group often preserves the memory while cutting the volume dramatically.
