Books weigh more than you think
Start here, because every shelf failure traces back to it.
A linear foot of paperbacks is about 20 pounds. Hardbacks are 25 to 30. So a four-foot shelf of books is 80 to 120 pounds — more than most people would hang a television on, resting on two brackets they chose because they looked nice.
| 4 ft shelf of | Weight |
|---|---|
| Ornaments and photographs | 5–15 lb |
| Kitchen crockery | 60–80 lb |
| Paperbacks | about 80 lb |
| Hardbacks or records | 100–120 lb |
Everything below follows from this: the span has to suit the material, and the fixings have to suit the load.
Span: how far a shelf can go without sagging
Unsupported span, for a shelf carrying books:
| Material | Max span |
|---|---|
| 3/4 in. particleboard or melamine | 24 inches |
| 3/4 in. plywood | 30 inches |
| 1 in. solid pine | 30–36 inches |
| 1 in. hardwood | 36–42 inches |
| Steel-reinforced floating shelf | per the maker, usually 36 in. |
Those are for books. Double them for ornaments.
The practical answer for a long run is more brackets, not a thicker shelf — a bracket every 24 to 32 inches, with the shelf overhanging no more than 4 inches past the end bracket. A sagging shelf cannot be straightened; it has taken a set and the only fix is replacing it or adding support underneath.
A front edge lip or a hardwood nosing glued to a plywood shelf stiffens it dramatically for very little money, which is how shop fitters get long spans out of thin material.
Fixings: why shelves come off walls
Two things hang a shelf and both have to be right.
A bracket into a stud will hold more than the shelf will. This is always the first choice, and it is why shelf positions are sometimes better decided by where the studs are than by where the shelf would ideally go.
With no stud available, the fixing has to be a snap toggle or heavy-duty toggle bolt — rated in the hundreds of pounds in half-inch drywall. Plastic expansion plugs are rated for a few pounds each and crumble the gypsum around them over months. They are the reason shelves fall off walls, usually at 3am, usually all at once.
Floating shelves are the demanding case. There is no bracket under the shelf, so the whole load acts in shear and bending at the wall face through a few steel rods. A floating shelf needs its rods in studs, or in heavy toggles with the shelf treated as decorative rather than structural. A floating shelf that droops at the front has not been overloaded so much as under-fixed.
What it costs
| Shelves | Total | Each |
|---|---|---|
| 1 | $150 | $150 |
| 2 | $215 | $108 |
| 10 | $725 | $73 |
Into hollow drywall with toggles, two shelves are $250; into plaster or masonry, $280. High work — above a stair, a double-height wall — adds 25%.
The shelf itself is not in that. A pine board is $15, a 36-inch floating shelf $30 to $120, and a made-to-measure hardwood shelf whatever the joiner charges.
Alcove shelves, closets and the jobs worth paying for
Three shelf jobs are worth a professional even if you own a drill:
An alcove. The two walls are never parallel and the back is never flat, so a shelf cut square leaves a gap at one end. The method is to template the alcove in cardboard, transfer it, and cut the shelf to the shape of the hole — which is twenty minutes of fiddling per shelf and is the difference between fitted and jammed in.
A closet system. Wire or melamine systems hang from a single rail screwed into studs, and the whole thing's integrity is that one line of screws. Getting it level and into studs is the job; the shelves themselves clip on.
Long runs and anything over a desk or a bed. A 10-foot run of shelving wants brackets at consistent spacing, all at the same height, into studs that are not evenly spaced. It is laying-out work rather than drilling work.
What you are paying for
Two shelves, brackets into studs, at $215:
| Labor, about 1.55 hours | around $87 |
| Brackets, anchors and screws | $28 |
| The visit | $45 |
| Overhead and margin | the balance |
Can you do it yourself?
Yes, with a stud finder, a level, a tape and the right fixings — and the fixings are the part to spend money on rather than the brackets.
The order that works: find and mark the studs; decide the height and mark a level line; fix the first bracket; hold the shelf on it with the level on top and mark the second bracket from the shelf rather than from the wall; fix the second; then load it and look at the front edge.
What to avoid: plastic plugs, a span longer than the table above allows, and relying on a shelf being level because the wall looks level.
Questions worth asking
- Where are the studs, and can the shelves go there?
- What is the wall made of?
- What will be on the shelves — books, or ornaments?
- How long is the span, and how many brackets?
- If floating: what are the rods fixed into?
- What are the fixings rated for?
- Is this an alcove, and will the shelf be templated?
- Does the shelf need a front nosing to stop it sagging?
- Is anything going above a desk or a bed?
- What else can go up on the same visit?
Common questions
How much does shelf installation cost?
About $215 for two shelves, or $108 each, including brackets and fixings but not the shelf itself. One on its own is $150 because of the minimum charge, and ten come to $725. Into hollow drywall with toggle fixings two shelves are $250, and into plaster or masonry $280 — on this job the fixing is most of the work.
How far apart should shelf brackets be?
Every 24 to 32 inches for a shelf carrying books, with no more than 4 inches of overhang past the end bracket. The right answer to a long shelf is more brackets rather than thicker material. A 3/4 inch particleboard shelf should not span more than 24 inches under books, plywood 30, one-inch pine 30 to 36 and hardwood 36 to 42 — double all of those for ornaments.
How much weight can a shelf hold?
It depends entirely on the fixing rather than the shelf. A bracket screwed into a stud will hold more than you will ever put on it. A snap toggle in half-inch drywall is rated in the hundreds of pounds. A plastic expansion plug is rated for a few pounds and degrades the gypsum around it over months, which is why shelves fixed with them come off walls. For reference, a linear foot of paperbacks is about 20 pounds and hardbacks 25 to 30.
Why do my shelves sag?
The span is too long for the material, and books are heavier than people expect — a four-foot shelf of paperbacks is about 80 pounds. A sagging shelf has taken a permanent set and cannot be straightened; the fix is a shorter span with an extra bracket, a stiffer material, or a hardwood nosing glued to the front edge, which stiffens a thin shelf dramatically for a few dollars.
Do floating shelves need to be in studs?
Ideally yes, because a floating shelf has no bracket under it — the entire load acts in shear and bending at the wall face through a few steel rods. Into studs, a floating shelf is as strong as any other. Into heavy toggles it will hold, but it should be treated as decorative rather than structural. A floating shelf that droops at the front is almost always under-fixed rather than overloaded.
What is the best fixing for shelves in drywall?
A stud if there is one. Where there is not, a snap toggle or a heavy-duty toggle bolt, which spread the load behind the board and are rated in the hundreds of pounds. Avoid plastic expansion plugs entirely for shelving — they are rated for a few pounds, they crumble the gypsum around them over time, and they are the single most common cause of a shelf failing.
How do I fit shelves in an alcove?
By templating, because the two walls are never parallel and the back is never flat — a shelf cut square leaves a gap at one end. Cut a cardboard template to the shape of the opening, transfer it to the shelf and cut to that line. It takes about twenty minutes per shelf and it is the difference between a shelf that looks fitted and one that looks jammed in. It is also the shelf job most worth paying somebody for.
How high should shelves be?
The lowest shelf in a living space usually sits above furniture, 8 to 10 inches clear of a sofa back. Above a desk, 20 to 24 inches above the surface keeps the working area usable. In a closet, a single top shelf goes about 80 inches up with the hanging rail below it. For books, 12 to 13 inches between shelves takes most hardbacks and 10 inches takes paperbacks, so plan the spacing around what is going on them.
How deep should a shelf be?
10 to 12 inches suits books, kitchen items and most general storage, which is why it is the common depth. Deeper than 12 inches and things get lost at the back; shallower than 8 and hardbacks overhang. In a closet, 14 to 16 inches is usual to take folded clothes and boxes. Remember the bracket has to be sized for the depth — a bracket shorter than two thirds of the shelf depth lets the front edge tip.
Can I install shelves myself?
Yes, with a stud finder, a level, a tape and good fixings — and spend the money on the fixings rather than the brackets. The order that works: mark the studs, mark a level line at the height you want, fix the first bracket, hold the shelf on it with a level on top and mark the second bracket from the shelf rather than the wall, fix that, then load it and look along the front edge. Avoid plastic plugs and do not exceed the span your material allows.
Is a closet shelving system a DIY job?
It is achievable but it is more exacting than it looks, because wire and melamine systems hang from a single rail and the whole thing's integrity is that one line of screws. Getting the rail level and into studs is the job; the shelves and rods clip on afterwards. If the closet walls are plaster or the studs are not where the rail needs fixing, it is worth paying somebody, since a system that pulls off a wall takes the clothes and part of the wall with it.
Is it cheaper to have several shelves fitted at once?
Substantially: $150 for one, $108 each for two, $73 each for ten. The minimum charge for a visit is most of a single shelf job, and once somebody is there with the tools out, each additional shelf is about 35 minutes. If there are shelves wanted in two rooms and a closet, that is one booking rather than three.
