Hanging hardware and wall load for frames and boards: what the ratings do and do not tell you

Every hung frame or board passes its weight through a chain: the artwork and frame, the hanger on the back, any wire between hangers, the nail, hook or anchor, and finally the wall.

Frame-side hardware may come with the product, while the wall-side fixing is chosen at installation, so this guide covers both. Check with the maker which hardware is included. For the materials the frame itself is made from, see frame materials compared.

The figures below come from manufacturer data sheets and retailer guides, and each is a rating under stated conditions. We did not open a standards body, museum or hanger-maker technical document for the hanger side, so the hanger figures are retailer or supplier examples, not standards.

A sawtooth hanger is a small metal strip with a series of teeth, screwed into the top centre of the frame back [3]. The same retailer places it about 1/2 inch from the top edge and names small screws, or the small finishing nails that often ship with the hanger, as fasteners [3]. A hanger supplier says sawtooth hangers suit lightweight wood-frame pictures [5].

D-rings are two D-shaped metal rings screwed into the back of the frame, one on each side [3]. The retailer measures down about one-quarter to one-third of the frame's height for placement, and describes small D-rings for frames under 10 lbs, medium for 10 to 25 lbs, and large for 25 lbs and over [3]. It pairs them with wire for heavier frames [3]. Our guide to D-rings, sawtooth and keyhole hangers covers placement and gallery practice in full.

Keyhole slots and screw eyes also exist. We found no ratings for them in the sources we opened, so we do not rate them here. If a design uses them, ask the hardware maker for a data sheet.

The sources do not agree on where sawtooth hangers stop being suitable. One retailer says that for anything over 5 pounds, D-rings with wire are more secure [3]. A picture-hanging supplier says sawtooth hangers are most suitable for wood-frame pictures and art weighing less than 25 pounds [5]. In our view that gap is a good reason to rely on the specific product's published rating rather than a rule of thumb. For frames longer than 24 inches, the same supplier suggests two or three sawtooth hangers [5].

A metal D-ring or hanger is a single manufactured part. The wall depends on what it is made of. The wing-anchor sheet we read gives separate load tables for drywall, hollow concrete masonry, clay brick and concrete [1], and the anchor supplier we read publishes different loads for each board thickness [2], so the usable figure changes from wall to wall.

Picture Hang Solutions advises checking the wall type compatibility of a hanger, and notes that a hanger that cannot carry the item can damage the wall [4].

For heavier pieces the framing retailer points to studs or a cleat, but its page is not consistent on the threshold. The quick answer says frames over 20 pounds need French cleats or D-rings driven into studs rather than sawtooth hangers in drywall, while other sections say frames over 25 pounds should hang from a stud or use heavy-duty anchors, or that a French cleat is the safest choice [3]. It is retailer guidance only, so treat the figures as a starting point.

Our buying guide for boards for offices and schools covers large boards, where wall fixing is often the main installation question.

Anchor data sheets give two kinds of load. One anchor supplier (Adit) defines tension as a force pulling the anchor out of the wall, perpendicular to the board, and shear as a force acting parallel to the board, downwards [2].

Our reading, not a claim from the sources: a frame hanging flat on a wall pulls mostly downward, so the shear figure is the closer match, while any outward pull adds tension. Check both figures, and use the lower one when you are unsure. For anchors by wall type, see our guide to drywall anchors, studs and masonry.

Start with the conditions, because the numbers mean nothing without them. The Adit page says its values are for a single fixing point with no spacing or edge-distance effects, and that two anchors close together do not give twice the load [2]. It does not mention a safety factor [2].

A US data sheet for a plastic wing anchor kit lists tension and shear by wall material and minimum embedment depth, then adds safe tension and safe shear columns. Its footnotes say the safe values are measured by a factor of 3.0 based on the tension values, and that shear values are modeled based on tension data [1]. The same sheet says these anchors are not recommended for overhead applications or where holding values are critical [1]. In 5/8 inch drywall the listed tension for the 2AK anchor is 87 lb, but for the 3AK anchor it is 75 lb, so a bigger kit is not always stronger [1].

The table below sets out the drywall rows from the wing-anchor sheet [1]. In our reading, the safe columns are the ones to compare against your load.

This example shows how to read the table columns. The frame weights are invented for illustration (illustrative figures, not from any source). The ratings come from the data sheet table above [1]. The 1.5 times margin is the framing retailer's advice to choose hardware rated for at least 1.5 times the total [3]. Stacking that margin on top of the sheet's own factor of 3.0 is our assumption: the sources do not say whether to combine them. Our guide on working out the total weight covers the weighing, and glazing choice changes that total, as our guide to acrylic versus glass glazing explains.

• Case A, a 10 lb frame. Case A is shown only to read the table, since [3] classes a 10 lb frame as a D-ring and wire piece. Required rating: 10 x 1.5 = 15 lb [3]. In 1/2 inch drywall, the 3AK anchor lists safe shear of 28 lb and safe tension of 17 lb [1]. Safe shear of 28 lb is above 15 lb, and safe tension of 17 lb is only just above it, so if the piece could be pulled outward, tension is the closer figure. This is not a recommendation to use that anchor.
• Case B, a 25 lb frame. Required rating: 25 x 1.5 = 37.5 lb [3]. The highest safe shear value in any drywall row of the sheet is 36 lb [1]. One anchor of this type does not cover 37.5 lb, and the sheet already says it is not for critical holding values [1]. The retailer's advice for heavier pieces is studs or a cleat [3].

This arithmetic is illustrative only and not a sizing method.

Do not fix the shortfall by adding up ratings. One hanger supplier says pound ratings are not cumulative, and gives a 40-pound picture on two regular sawtooth hangers as its example [5]. Check the maker's own guidance before assuming two fixings share a load equally.

Two ideas keep ratings in perspective.

• A rating is conditional. One supplier defines a weight rating as the maximum weight a hanger or wall hook can support [4]. If your wall, installation or load direction differs from the tested conditions, the rating may not apply directly.
• Margins are advice, not standards. The 1.5 times figure, the D-ring size classes and the stud and cleat thresholds come from one retailer [3]. We did not open a standard behind any of them, and one anchor sheet uses a factor of 3.0 [1] while the Adit page states none [2]. For the hanger side, see the frame-side hardware section, where the sources disagree on 5, 20 and 25 lb.

Our view, not from a source: a wire, hanger and anchor each have their own rating, and the lowest one limits the system. For public spaces, schools and offices, ask a qualified installer to specify the fixing for the actual wall. This guide is general information, not engineering advice.

1. Work out the total weight of the finished piece [3].
2. Identify the wall: plasterboard, brick, concrete or masonry, and match the fixing to it [1][4].
3. Choose the wall-side fixing first, and read its conditions: board thickness, anchor size, embedment and setting tool [1][2].
4. Compare the load with the safe or recommended value for both tension and shear, using the lower one when direction is uncertain [1][2].
5. Choose frame-side hardware to match the weight (see the frame-side hardware section, where the sources disagree on 5, 20 and 25 lb) [3][5].
6. Space the hangers: two or three sawtooth hangers for frames longer than 24 inches [5].
7. Keep a margin, and record which data sheet each figure came from.

If you are briefing a frame or board order, add hanging hardware to the brief. As a suggestion, not a sourced rule, the brief could state the hanger type, the number and position of hangers for each size, and the maximum frame weight to print on the carton or insert. When you write the brief, see how to brief a frame or board order for where hanging hardware fits.
