In a small room the constraint is never budget. It is a 24 inch gap beside a door and a sloped ceiling over the only free wall.

The short answer
Go up, go under, and go narrow. In a small room the three underused spaces are vertical wall above about 4 ft, the floor under the desk, and gaps under 30 in wide that standard furniture ignores. The specific products: a 23.6 in wide 5-tier shelving unit, a 36 in high cabinet that fits under a window, and 11 dollars of drawers mounted to the underside of the desk.
Measure the gaps, not the room
A small room is not uniformly small. It has a few usable gaps, and the dimensions of those gaps rule out most furniture before price enters into it.
01Every clear wall run, including skirting board, radiator pipes and door architrave. Write down the narrowest.
02Height to any obstruction on each of those runs: a window sill, a dado rail, a sloped ceiling, a light switch.
03Desk apron clearance, floor to the underside of the desktop. Measure on the carpet if there is carpet.
04Door swing. The arc a door sweeps is unusable floor, and in a small room it is often a quarter of it.
Those four numbers eliminate most of the market immediately, which is a relief rather than a problem.

Going up
Wall above about 4 ft is usually completely unused in a home office, because furniture is floor-standing and pictures are hung at eye level.
Tall narrow shelving is the obvious answer and comes with a real caveat. The NUMENN at 23.6 in wide and 60.4 in tall gives five tiers in 2 sq ft of floor, and it weighs 25.3 lb with a published 30 lb per panel. A loaded top shelf on a 25 lb frame is exactly the configuration that comes forward, which is why it ships an anti-tilt tool and why you must fit it.
Thirty pounds a shelf is one banker's box, so tall shelving in a small room is for books, binders and light things rather than for archive. The load arithmetic is on best office shelving.
Going under
The space under a desk is dead space in almost every home office, and in a small room it is the largest unused volume you have.
Mounted drawers, 11 dollars. Adhere to the underside of the desktop, cost no floor and no surface, hold stationery. The single best value on this site.
A cart on one side, about 15 by 18 in. Leaves two-thirds of the knee space clear, which is the normal and correct use.
A short cabinet under the desk, if the apron clears it. Only one lateral in our set at 27.95 in does.
What does NOT go under a desk in a small room: an archive, a printer, or anything you have to move the chair to reach. Under-desk storage ideas has the measured version.
The short cabinet nobody thinks of
A 36 in high steel cabinet is the most underrated product for a small room. It fits under a window, under a sloped ceiling, and along a wall with a radiator - all places a 71 in cabinet cannot go.
It publishes 180 lb per shelf, which is the same as the 72 in version, so it genuinely archives where shelving cannot. And it gives you a 32 by 16 in surface at a usable height, which in a small room is a second desk, a printer stand or somewhere to put a lamp. About 84 dollars, and it is on best office storage cabinets.
The non-furniture answers
Three things that are free or nearly, and that a small room benefits from more than a large one.
01Own less paper. Scanning and shredding typically removes more than half a household's filing volume, which in a small room is the difference between needing a cabinet and not. A document filing system for a home.
02Use the door swing. The arc behind a door is unusable floor and perfectly usable WALL. A shallow 6 in shelf unit on the wall the door opens against costs nothing in floor area.
03Reconfigure what you own. Both Furinno cube units stand tall or lie long, which is two pieces of furniture from one purchase. A unit lying under a window with a surface on top is often better in a small room than the same unit standing.

Five tiers in a 2 sq ft footprint
FSC-certified wood panels on a steel frame
Anti-tilt hardware included, and at 60.4 in and 25.3 lb you need it
What they are not
30 lb per panel is the lowest rating in this hub: one box of paper, and only just
25.3 lb for a 60.4 in unit is very light, which is why the anti-tilt tool is not optional
11.81 in deep will not take a letter box front-on
No total load published
Skip this if
Skip this if the shelves will hold anything heavy. At 30 lb per panel it is a display and book unit, and a loaded top shelf on a 25 lb frame is exactly the configuration that comes forward.
Who it is for. A narrow alcove that needs height and will hold books and boxes of light things.

Paper capacity
About 6 banker's boxes per shelf, from the 180 lb rating
Our arithmetic at about 30 lb per full letter-size banker's box
What the specs are good for
180 lb per shelf, matching the 72 in INTERGREAT, in a cabinet half the height and a third of the price
36 in high fits under a window or a sloped ceiling, where a 71 in cabinet cannot go
A usable 36 in work surface on top at standing-desk-ish height
Shock-absorbing feet, which protects both the floor and a wobbly cabinet
No wall anchor needed at this height and weight
What they are not
Two shelves only, so three bays total. Capacity is a third of the tall cabinets
46 lb empty with 360 lb of rated shelf capacity, which is a lot of load on a light shell
Single key lock rather than a 3-point system
No total load published, only the per-shelf figure
Skip this if
Skip this if you need volume. Three bays is roughly 18 boxes at the published rating, and if that is enough the cabinet is excellent; if it is not, the 72 in version is the only answer.
Who it is for. A room with a window, a radiator or a sloped ceiling along the only free wall.

What the specs are good for

Bostitch is an actual office-products brand with a product line behind it
What they are not
No published load rating, and adhesive mounting under a desk is exactly where you want one
1.91 in deep: this holds stationery, not notebooks or anything with a spine
Self-adhesive only, no screw option, so removal will take finish with it
Needs a smooth flat underside, which a desk with a frame rail or a cable tray may not have
Skip this if
Skip this if your desk underside is textured, has a visible frame, or is anything other than a flat smooth panel. Adhesive drawers come off, and they come off full.
Who it is for. Every desk. This is the first eleven dollars we would spend on a cluttered one.
One worked example, because the abstract advice is harder to act on.
Under the desk: mounted drawers, 11 dollars. Zero floor.
Beside the desk, in a 15 in gap: Staples 3-drawer vertical, about 107 dollars, 47.7 filing inches.
Under the window: CJF 36 in cabinet, about 84 dollars, three bays at 180 lb each, plus a 32 in surface on top.
On the wall above the desk: nothing. Keep one wall clear for acoustic panels if calls matter, because a small hard room is a reverberant one. Best acoustic panels for a home office.
That is about 200 dollars, uses three different unused spaces, and leaves the floor walkable. If the room is also shared, how to divide a room for a home office covers the layout side, and tidyandstow.com covers small-space storage beyond the office.
FAQ
Questions people ask about this
How do you store things in a small home office?+
Use the three spaces small rooms leave empty: vertical wall above about 4 ft, the floor under the desk, and gaps under 30 in wide that standard furniture ignores. A tall narrow shelving unit, mounted under-desk drawers and a 36 in cabinet under a window cover all three.
What is the narrowest file cabinet that holds a useful amount?+
The 3-drawer vertical at 14.3 in wide, giving about 47.7 linear filing inches. That is more filing than most 2-drawer laterals in half the wall run. It needs about 32 in of clear floor in front with the drawer out.
Can tall shelving hold boxes of paper in a small room?+
Usually not. Narrow tall shelving publishes around 30 lb per shelf, which is one banker's box, and most is under 12 in deep so a box will not sit front-on anyway. For archive in a small room, a 36 in steel cabinet at 180 lb a shelf is the right product.
What fits under a desk in a small office?+
Mounted drawers on the underside, which take no space at all, and a cart or short cabinet on one side about 15 by 18 in. Keep two-thirds of the knee space clear. Nothing you have to move the chair to reach will get used.
How can I store more without buying furniture?+
Own less paper: scanning and shredding typically removes over half a household's filing volume. Use the wall behind the door swing, which is unusable floor and perfectly good wall. And reconfigure what you have, since reversible shelving units are two pieces of furniture in one.

Our arithmetic: the weight of office paper
A standard letter-size banker's box holds about 2,500 sheets; 2,500 sheets of 20 lb bond weighs about 25 lb, so a full box is roughly 30 lb including the box. That works out at about 1.5 lb per linear inch of upright files. Every shelf-load and cabinet-load comparison on this site uses those figures and shows the sum.
Our arithmetic: the 3 in shell allowance for filing capacity
Only one cabinet in our set publishes a drawer interior — the BIZOEIRON lateral, at 32.44 in interior inside a 35.43 in exterior, a 2.99 in difference. We round that to 3 in and apply it to every other cabinet's published external figure. It is derived from one lateral cabinet, so applying it to verticals is an assumption and we label it as one every time.
