How to organise a storage unit so you can find anything in it
A practical plan for packing, laying out and recording a self storage unit, so finding one item takes minutes, not an afternoon of unstacking boxes.
Updated 3 November 2026 · By the FindMyItem team at Railstons GmbH
The secret to a storage unit you can actually use is deciding where things go before you carry anything in, and writing down what is in every box. Most units become a wall of identical cardboard because people pack fast, stack fast and promise themselves they will sort it out later.
Here is a plan that takes a little longer on the day and saves hours every visit after.
Before moving day
- Measure the unit. Note the width, depth and height, and where the door opens. A unit that is 3 metres deep has very different rules from one that is 1.5 metres deep.
- Plan an aisle. In anything bigger than a locker, leave a walkway from the door to the back. Without one, the only box you can reach is the one at the front.
- Decide on shelving. Freestanding shelves let you use the height of the unit and pull out one box without moving five. Check whether your storage company allows them.
- Sketch zones. Split the unit into a few areas, for example "left wall", "back" and "right wall". Keep the zone names short; you will use them a lot.
Packing for storage
- Use boxes of the same few sizes. They stack straight and make the most of the space.
- Choose plastic tubs for anything that matters. Cardboard softens in damp and attracts pests. Clear tubs let you see inside; solid ones keep light off fabrics and photos.
- Put heavy things at the bottom and never pack a box heavier than you can lift above your head.
- Wrap and bag soft furnishings. Breathable covers work better than plastic, which can trap moisture.
- Keep a few boxes empty and flat for anything you bring back later.
Laying out the unit
- Put the things you will want soonest at the front, near the aisle: seasonal clothes, sports kit, documents.
- Put furniture and long term items at the back and along the walls.
- Stand mattresses and sofas on their ends to save floor space, if they will tolerate it.
- Leave a small gap between boxes and the walls for air.
- Take a photo of each wall once you are done. It is a surprisingly useful map.
Record what is in every box
This is the step that makes the rest work, and the one most people skip. You need to know three things about every item: which box it is in, where that box sits, and which place it is at.
You can do it on paper: number every box, list its contents in a notebook, and tape a copy of the list inside the unit door. It works until you need something while you are at home, the list is in the unit, or you take one thing out and forget to cross it off.
An app solves those problems because the list travels with you and you can search it. Our guide to QR code labels for storage boxes explains how to label the boxes.
Keeping it organised
- One in, one out. When you take something home, update the record before you leave.
- Note what is out. If you borrow the tent for a weekend, mark it as out so you do not drive across town to fetch it.
- Check once a year. Open the boxes nobody has touched for a year. You may be paying to store things you no longer want.
How FindMyItem helps with a storage unit
FindMyItem was built for things kept in more than one place.
- Add the storage unit as a place. It gets a pin on a map, and one tap gives directions in Apple Maps or Google Maps.
- Split it into areas that match your zones, such as "Back wall" or "Shelf 2".
- Print a QR label for every box and photograph items into it as you pack.
- At home, type "ski gloves" and see "Box 7, back wall, storage unit" before you set off.
- Mark items as out when you take them home. They drop out of normal searches but stay in one list, with a one tap way back.
- A To do list flags boxes that have not been checked for a year.
It also works without a signal, which matters in a concrete storage building. With Pro you can share the unit with up to 5 other people (6 including you), each a Viewer or an Editor, and there is no charge for additional users, so anyone in the family can look things up. The free plan covers 3 places and 100 items. FindMyItem is on iPhone for now (iOS 16 or later); Android and iPad versions are coming.
