How to store drawings and sketchbooks depends on whether you’re protecting loose sheets or bound books, but the basic idea is the same: keep the paper supported, dry, clean, and away from prolonged light. Loose drawings generally do best stored flat inside archival folders or boxes, while most sketchbooks can be kept upright on a supported shelf or placed flat if they’re large, heavy, or especially valuable.
I have sketchbooks and drawings that I want to keep for years rather than treat as disposable studies, so I tend to think about storage as part of taking care of the work itself. You don’t need a museum storage room to do this well. A closet shelf, archival box, portfolio, or dedicated drawer can work perfectly well if the environment around it is stable.
The Best Way to Store Drawings and Sketchbooks
The biggest distinction is between loose drawings and sketchbooks.
Loose drawings need physical support because individual sheets can bend, curl, crease, tear, or rub against one another. Sketchbooks already have some protection from their covers and bindings, so storing them is usually more straightforward.
For most of my work, I would choose a dry interior room or closet rather than a garage, basement, attic, or other area that experiences big changes in temperature and humidity. I also keep artwork away from windows and direct sunlight.
If you’re choosing paper and materials with longevity in mind from the beginning, you can also see my guide to drawing supplies.
How to Store Drawings on Paper
For loose drawings, my preference is flat storage whenever possible. Place the drawings inside acid-free, lignin-free folders and then put those folders inside an archival box, portfolio, or flat drawer.
This protects the paper from dust and handling while also reducing the chance of bent corners and creases. It is particularly useful if you’re storing original drawings that you may eventually frame, sell, scan, or exhibit.
If you want transparent sleeves, look for archival-quality materials intended for storing works on paper rather than ordinary office sheet protectors. The enclosure should support the drawing without squeezing it or forcing it into a space that’s too small.
I would also avoid putting loose drawings directly against ordinary cardboard, inexpensive backing boards, newspaper, or other unknown papers for long periods. Storage materials themselves can deteriorate and transfer acids to the artwork over time.
How to Store Large Drawings
Large drawings are where storage gets more difficult. If possible, store them flat in an oversized archival portfolio, flat file, or large archival box. This keeps the paper supported across its entire surface rather than allowing it to sag or curl.
Avoid folding a drawing simply to make it fit into a smaller container. Once a fold has been pressed into paper, it can be difficult to remove completely.
If you’re building up a larger collection of work on paper, grouping drawings by approximate size also makes storage easier because small sheets are less likely to shift around beneath much larger ones.
How to Store Sketchbooks
Sketchbook storage is simpler because the binding and covers already give the drawings some protection.
Most normal-sized sketchbooks can be stored upright on a bookshelf as long as they’re properly supported and aren’t leaning heavily to one side. I like this option because the books remain accessible. I can pull one down whenever I want to look through old drawings rather than forgetting about everything inside a storage box.
Don’t pack the shelf so tightly that removing one sketchbook damages the neighboring books. On the other hand, leaving them loosely leaning at an angle isn’t ideal either. A bookend can help keep everything vertical.
Large, unusually heavy, fragile, or valuable sketchbooks can be stored flat. If the sketchbook has delicate attachments, collage elements, or pages that have made the book swell unevenly, flat storage can also place less stress on the binding.
For sketchbooks I want to protect more carefully, an archival box gives another layer of protection from dust, light, and accidental damage.
Humidity Matters More Than the Storage Box
You can buy an expensive archival box and still have problems if you keep it somewhere damp.
High humidity encourages mold and can cause paper and bindings to distort. Very large swings between dry and humid conditions aren’t ideal either, so I would prioritize a reasonably stable interior environment over obsessing about one perfect humidity number.
The Northeast Document Conservation Center’s environmental guidelines recommend relatively dry and stable conditions for paper and book collections.
If you live somewhere consistently humid, controlling the humidity of the room is more useful than simply throwing moisture-absorbing packets into every box.
Silica-gel desiccant packs can still be useful inside some enclosed storage containers, but they aren’t a substitute for keeping the collection itself somewhere dry. They also eventually become saturated and need to be replaced or regenerated.
Keep Drawings Away From Sunlight
Drawings sitting in storage don’t need to see daylight. In fact, darkness is one of the simplest forms of protection you can give them.
Light damage is cumulative. UV radiation and visible light can contribute to fading, yellowing, weakening of paper, and changes in drawing media over time. This is why a shelf across from a sunny window isn’t where I would keep an important group of sketchbooks.
A closed archival box, cabinet, drawer, or dark closet protects artwork far better than leaving it continuously exposed in a bright room.
Storing Pencil, Graphite, and Charcoal Drawings
The storage environment is only part of the problem with graphite, pencil, charcoal, and other easily smudged media. You also need to prevent the drawing surface from rubbing against whatever is above it.
I wouldn’t stack a pile of loose charcoal or soft graphite drawings directly against one another. Instead, give delicate work its own archival folder or use an appropriate archival interleaving material so the drawing surface isn’t constantly being rubbed when the stack is moved.
Be especially careful with very soft charcoal. A storage sleeve or folder protects the sheet only if putting the drawing into it doesn’t drag another material across the surface.
If pencil is your main concern, I go into that subject separately in my guide on how to preserve a pencil drawing.
Portfolios, Drawers, Boxes, or Bookshelves?
There isn’t one storage system that works for every artist. I think it’s more useful to choose one based on how often you actually look at the work.
Bookshelves make sense for sketchbooks you use regularly. Archival boxes are better for work you want protected and don’t need to access constantly. Portfolios are useful for loose drawings that you still want to browse easily, while flat drawers are one of the best solutions once you have a larger collection of individual sheets.
A closet can work extremely well too. I would rather have a simple archival box on a high shelf in a dry interior closet than an elaborate storage system sitting in a damp garage.
Places I Would Avoid Storing Drawings
Attics, garages, unfinished basements, sheds, and areas directly beside exterior windows are generally poor choices because they tend to experience greater changes in temperature or humidity.
Under-bed storage can work if the room itself is dry and the drawings are inside a protective box, but I wouldn’t slide loose artwork directly beneath a bed where it can collect dust, get kicked, or be accidentally crushed.
I would also keep artwork away from plumbing whenever possible. A perfectly dry cabinet isn’t very helpful if it’s directly beneath a pipe that eventually leaks.
Don’t Forget to Make a Digital Copy
Good physical storage protects the original, but I also like the idea of having a digital record of important sketchbook pages and finished drawings. It gives you another copy if the original is ever damaged and makes it much easier to revisit older work without repeatedly handling it.
If you have years of books piling up, here’s how I approach digitizing sketchbook pages.
A Simple Storage Setup Is Usually Enough
You don’t need to turn your home into a conservation archive to store drawings properly. For most artists, a dry interior space, protection from light, good-quality folders or boxes, and sensible handling will solve most of the common problems.
For loose drawings, I would prioritize flat, supported storage. For everyday sketchbooks, a supported bookshelf is usually fine. For anything especially important, fragile, or difficult to replace, an archival enclosure gives you another layer of protection.
The goal isn’t to hide your work away forever. It’s simply to store it well enough that when you pull a drawing or sketchbook out years from now, it still looks and feels like the work you originally put away.
