A framed print can last decades or cockle within a season, and the difference usually comes down to three decisions made before the hook goes in: what the print is mounted against, what sits between it and the light, and where on the wall it ends up. Get those right and a favourite piece can live happily on a cold Victorian wall, coming down years later in the condition it went up.
Start with the mount, not the frame
The frame is the part everyone notices; the mount is the part that saves the print. Ask for conservation-grade, acid-free mount board — sometimes called museum board — with a neutral pH. Ordinary mount board is often acidic and will slowly burn a brown line into the paper where it touches, a stain known as foxing that no amount of cleaning will remove.
A window mount, where the board overlaps the print's edges and holds it clear of the glass, does two jobs: it stops the paper touching the glazing, and it creates a small air pocket that softens swings in temperature and humidity. Never let a print sit flat against glass. In a cold room, condensation forms on the inside of the glass and can transfer straight into the paper.
Attach the print to the backing with hinging tape or photo corners, not with glue. Museum hinges — thin strips of Japanese paper and a starch paste — hold securely but release with moisture if the print ever needs to come out. Linen tape hinges are a good practical alternative. Keep tape off the face of the print, and never use masking tape, sticky tape, spray adhesive or dry mounting; all are difficult or impossible to reverse.
Back it properly, too. A rigid, acid-free backing board keeps the print flat and blocks dust. If the frame is going on an outside wall, a moisture-barrier board behind the mount is worth the small extra cost.
Handle it as little as possible
Skin oils are surprisingly damaging to paper and inks. Hold the print by its edges, or wear clean cotton gloves, and work on a wiped-down surface. If you are reframing an existing piece, check the old mount for acid damage while you have it apart.
Glazing, UV and everyday light
UV-filtering glass and acrylic block most of the ultraviolet light that comes through a window. They do not stop fading. Visible light, heat and humidity all do their own damage over time, so a print behind the best glazing will still fade if it hangs in direct sun.
Keep artwork off walls that take direct sunlight, especially around midday. Avoid hanging anything above a radiator, where heat and rising dust do the most harm. Rotate prints in bright rooms so no single piece takes years of exposure. Acrylic is lighter and safer for large frames but scratches more easily; glass is heavier, which matters when you come to choose a fixing. If a print is valuable, ask a qualified framer about the options and speak to a conservator before making changes.
The right height for a UK room
The usual guide in galleries and most British homes is to put the centre of the artwork at roughly 145–152 cm from the floor. That is about eye level for an adult of average height, and it feels comfortable whether you are standing in a hallway or sitting in a living room.
Above a sofa or sideboard, measure the gap: leave about 15–25 cm between the top of the furniture and the bottom edge of the frame. Too small and the artwork looks squashed; too large and it floats. When hanging a group, treat the whole arrangement as one shape and centre it on the same line. On stair walls, follow the rake of the stairs rather than a level line.
Fixings that suit your wall
A frame that falls takes the print with it, so the fixing matters as much as the frame.
- Weigh the frame. Bathroom scales will do, then choose fixings rated well above that weight.
- Use two hooks, not one. Two points stop the frame tilting and twisting, and halve the load on each. Position them so the hanging wire forms a wide, shallow angle rather than a tight V.
- Match the fixing to the wall. Plasterboard needs hollow-wall anchors or a timber stud. Brick and block need a masonry bit and the right plug. Older lath-and-plaster can crumble; a toggle fixing spreads the load behind the lath.
- Check what is behind the plaster. A cable and pipe detector costs little and saves a great deal of trouble.
- Go heavy duty for heavy frames. Above roughly 5 kg, consider a French cleat or a Z-bar screwed into studs or masonry rather than wire.
Hanging prints on cold, damp walls
Plenty of British homes have solid brick or stone external walls that run cold in winter. Warm air inside meets that cold surface and condenses, and a frame pressed flat against it traps the moisture behind the backing board. In time you get musty smells, tide marks on the mount and mould on the wall you cannot see.
Where you can, hang on an internal wall. Where you cannot, keep an air gap: self-adhesive bumpers on the back corners of the frame hold it a few millimetres off the plaster and let air move behind. Check the wall behind the frame every few months, especially in winter. A cheap hygrometer tells you what the room is doing, and prints are happiest around 40–55% relative humidity. If a wall is genuinely damp, treat the cause — a leaking gutter, a blocked airbrick, poor ventilation — rather than hoping the frame will cope. A small dehumidifier helps, and moving a valuable print is a better answer than fighting a wet wall. For anything of real value, take professional conservation advice.
Before the drill comes out
- Mount is acid-free, and the print is held clear of the glass.
- Frame weighed, fixing chosen with a generous margin.
- Two hook positions marked, checked with a spirit level.
- No pipes or cables where you plan to drill.
- Centre of the artwork at roughly 145–152 cm, or the right gap above the furniture.
- Air gap planned behind the frame if the wall runs cold.
Looking after it once it is up
Dust the frame with a dry microfibre cloth. Clean glass by spraying the cloth rather than the glass, so nothing runs down behind the frame. Check the wire and its knots once a year and replace anything frayed. Rotate prints in bright rooms so the exposure is shared. And if you ever take a print down and find a mark on the wall behind it, treat that as information: the wall is telling you something about damp, and the next print will fare no better.
