From Snuug, the iPhone room app. en-gb Sun, 01 Nov 2026 09:00:00 GMT https://snuug.app/guides/12x12-living-room-layout https://snuug.app/guides/12x12-living-room-layout Sun, 01 Nov 2026 09:00:00 GMT Guides In a 12 × 12 ft (366 × 366 cm) room, a sofa against one wall puts you about 119 in (10 ft, 302 cm) from a TV on the opposite wall: right for a 65–75 in screen. Float an 84 in sofa 36 in off the wall, with the walkway behind it, and you sit about 83 in away: right for 55–65 in . Use a 6 × 9 ft or 8 × 10 ft rug, and keep the main walkway 30–36 in wide. https://snuug.app/guides/3x3-bedroom-layout https://snuug.app/guides/3x3-bedroom-layout Sun, 01 Nov 2026 09:00:00 GMT Guides A double bed (135 × 190 cm) fits a 3 × 3 m bedroom. Centred on a wall, on a frame, it leaves about 77 cm each side and 95 cm at the foot , just over the 76 cm Which? suggests. A standard 58 cm deep wardrobe does not fit at the foot: it leaves only 37 cm. Put the wardrobe in the corner beside the headboard, push the bed against one wall, or choose a 35 cm deep wardrobe. https://snuug.app/guides/3x4-living-room-layout https://snuug.app/guides/3x4-living-room-layout Sun, 01 Nov 2026 09:00:00 GMT Guides Put the sofa on a 4 m wall and the TV on the wall opposite. Across the 3 m width, a 90 cm deep sofa, a 40 cm gap, a 45 cm coffee table, a 90 cm walkway and a 35 cm TV unit add up to exactly 300 cm. A 200 cm sofa takes a 160 × 230 cm rug, and from it you sit about 2.35 m from the screen, which suits a 55–65 in TV. https://snuug.app/guides/4x4-living-room-layout https://snuug.app/guides/4x4-living-room-layout Sun, 01 Nov 2026 09:00:00 GMT Guides A 4 × 4 m room is 16 m², close to the 17.1 m² average for a living room in a new British home. With the sofa against a wall you sit about 3.3 m from a TV on the opposite wall, which suits a 75 in screen. Float the sofa 100 cm out, with the walkway behind it, and you sit about 2.3 m away: right for 55–65 in . A 200 × 290 cm rug suits most sofas here. https://snuug.app/guides/bedroom-layout https://snuug.app/guides/bedroom-layout Sun, 01 Nov 2026 09:00:00 GMT Guides Put the head of the bed on a solid wall, with no door or window in it, and leave 60–75 cm beside the bed and 75–90 cm at its foot. Approved Document M uses 750 mm in new accessible homes. A UK double is 135 × 190 cm and a king 150 × 200 cm , so a 3 × 3 m room takes a double and a wardrobe, and a king is easier from about 3 × 3.5 m. https://snuug.app/guides/box-room-ideas https://snuug.app/guides/box-room-ideas Sun, 01 Nov 2026 09:00:00 GMT Guides A 2.4 × 3 m box room (7.2 m²) takes a single bed (90 × 190 cm) with a wardrobe or a desk, or a small double (120 × 190 cm) in a corner with 70 cm beside it. Push the bed's long side against a wall to free a strip of floor 115–145 cm wide, keep the door's swing clear, and choose sliding or 35 cm-deep storage. https://snuug.app/guides/curtain-pole-height https://snuug.app/guides/curtain-pole-height Sun, 01 Nov 2026 09:00:00 GMT Guides Fit the curtain pole at least 15 cm (6 in) above the window frame , as UK shops advise, or higher: designers often go two thirds of the way to the ceiling . Let the pole run 15–20 cm (6–8 in) past each side , or 25–30 cm for heavy or pencil pleat curtains. Then match the drop. For eyelet curtains to the floor, the top of the pole sits at the drop plus 1 cm, so a 229 cm ready-made curtain needs the pole top at 230 cm : 10 cm below a 2.4 m ceiling. https://snuug.app/guides/decorate-rented-flat https://snuug.app/guides/decorate-rented-flat Sun, 01 Nov 2026 09:00:00 GMT Guides Start with the changes that need no permission and leave no mark: move the furniture, add lamps and warm bulbs, put down a rug big enough for the sofa's front legs, and lean art instead of hanging it. In England, private tenants usually need the landlord's written agreement to paint or drill, so ask first and keep it in writing. https://snuug.app/guides/feng-shui-bedroom-layout https://snuug.app/guides/feng-shui-bedroom-layout Sun, 01 Nov 2026 09:00:00 GMT Guides In feng shui, the tradition holds that the bed belongs in the commanding position : you can see the door from the bed, you are not lying in line with it, and the headboard is against a solid wall with no window behind it. In most UK bedrooms that means the wall opposite or beside the door, towards the far corner. Feng shui is a tradition, not a science. https://snuug.app/guides/first-home-checklist-uk https://snuug.app/guides/first-home-checklist-uk Sun, 01 Nov 2026 09:00:00 GMT Guides Before moving day, measure every room, door, hall and stair, and write the clear width of each door (about 70–72 cm on a standard 762 mm UK door). Buy a bed, curtains or blinds and two or three lamps first. Wait on the sofa, rug, art and paint until you have lived in the rooms for a few weeks and know where the light falls and where you walk. Fit a smoke alarm on every level and test it monthly. https://snuug.app/guides/how-to-make-a-room-cosy https://snuug.app/guides/how-to-make-a-room-cosy Sun, 01 Nov 2026 09:00:00 GMT Guides Switch off the ceiling light and light the room with three lamps at different heights , all with warm white bulbs of 2700 K . Pull the seats in, so the coffee table sits 35–45 cm from the sofa, and put down a rug big enough for the front legs of every seat: about 160 × 230 cm for a 200 cm sofa. Then keep a throw and cushions where you sit. The first moves are free, and every one is renter-safe. https://snuug.app/guides/how-to-make-a-room-look-bigger https://snuug.app/guides/how-to-make-a-room-look-bigger Sun, 01 Nov 2026 09:00:00 GMT Guides Clear the line of sight from the door to the far corner, keep the walkway 75–90 cm wide, and swap bulky pieces for fewer, lower ones on legs. Use a rug big enough for the sofa's front legs (about 160 × 230 cm for a 200 cm sofa), hang a mirror beside or opposite the window, and fit the curtain pole at least 15 cm above the frame, with curtains to the floor. Light the corners: paint helps less than people think. In one study, bright walls made a 4.5 m room look only about 8 cm wider. https://snuug.app/guides/living-room-clearances https://snuug.app/guides/living-room-clearances Sun, 01 Nov 2026 09:00:00 GMT Guides Walkways 75–90 cm . Sofa to coffee table 35–45 cm . Rug 15–20 cm past each end of the sofa, with 30–45 cm of bare floor to the walls. TV 1.2–1.6 times its diagonal from your eyes, centre at seated eye height (about 100–110 cm). Art centred 145–150 cm from the floor. These are designers' rules, not laws. https://snuug.app/guides/living-room-layout-with-tv https://snuug.app/guides/living-room-layout-with-tv Sun, 01 Nov 2026 09:00:00 GMT Guides Put the TV on a wall at right angles to the window , not opposite it, with the sofa facing it. Sit 1.2–1.6 times the screen's diagonal away (about 1.7–2.3 m for a 55-inch TV), with the centre of the screen at seated eye height, about 100–110 cm (40–43 in). Keep the main walkway 75–90 cm wide. Beside a chimney breast, a TV in the alcove stays at eye height. Above it, the top of the screen usually ends up more than 15° above your eyes. https://snuug.app/guides/long-narrow-living-room-layout https://snuug.app/guides/long-narrow-living-room-layout Sun, 01 Nov 2026 09:00:00 GMT Guides Run one walkway, 75–90 cm wide, down one long side and split the rest of the length into two zones, such as sitting and dining. Float the sofa across the room to face a TV on the end wall, or put its back to the walkway. In a 3 m wide room, a sofa on the long wall uses every centimetre: a 90 cm sofa, a 40 cm gap, a 45 cm table, a 90 cm walkway and a 35 cm TV unit make exactly 300 cm. https://snuug.app/guides/magnolia-walls https://snuug.app/guides/magnolia-walls Sun, 01 Nov 2026 09:00:00 GMT Guides Magnolia is a warm, light cream, so it works best with warm and earthy colours: sage, olive, navy, terracotta, dusty pink and mustard, with oak, walnut, rattan and brass. Light it with warm white bulbs of 2700–3000 K , all the same colour. Take care with brilliant white and cool blue-greys beside it, which can make it look yellow. If you rent and want to paint, ask the landlord first and get the answer in writing. https://snuug.app/guides/small-living-room-layout https://snuug.app/guides/small-living-room-layout Sun, 01 Nov 2026 09:00:00 GMT Guides Keep the main walkway about 90 cm wide (75 cm at the least), leave 35–45 cm between the sofa and the coffee table, and choose a rug that runs 15–20 cm past each end of the sofa. Put the sofa on the longest unbroken wall or float it to make a zone, and keep the door's swing and the radiator clear. https://snuug.app/guides/warm-white-vs-cool-white https://snuug.app/guides/warm-white-vs-cool-white Sun, 01 Nov 2026 09:00:00 GMT Guides Warm white is 2700–3000 K , cool white is about 4000 K , and daylight is 5000–6500 K . Lighting shops and designers usually suggest warm white for living rooms, bedrooms and dining rooms, and cooler white for kitchens, bathrooms and desks. Studies have not found that one colour makes a room more pleasant for everyone; having enough light seems to matter more. https://snuug.app/guides/why-room-looks-wrong https://snuug.app/guides/why-room-looks-wrong Sun, 01 Nov 2026 09:00:00 GMT Guides Usually it is something you can measure. The rug is too small (it should reach under the sofa's front legs and run 15–20 cm past each end). The art is too high (centre at 145–150 cm , or 15–25 cm above the sofa). Everything is pushed against the walls. One ceiling light does all the work instead of three sources . The sofa is far from two thirds of its wall. The curtain pole sits on the frame instead of 10–15 cm above it. Or two whites clash. https://snuug.app/guides/will-it-fit https://snuug.app/guides/will-it-fit Sun, 01 Nov 2026 09:00:00 GMT Guides A piece fits when three things pass. The room: its footprint plus the space to use it, with a 75–90 cm walkway left and every door and drawer able to open. The wall: a sofa about two thirds of the wall behind it. The way in: the piece's depth, height or diagonal depth under the clear width of every door on the route (about 70–72 cm on a standard 762 mm UK door), with 5 cm to spare. Then tape the footprint on the floor and live with it for two days. https://snuug.app/tools/bagua-map https://snuug.app/tools/bagua-map Sun, 01 Nov 2026 09:00:00 GMT Tools In the Western (BTB) school of feng shui, the tradition holds that you stand in the doorway, look in, and split the room into a 3 × 3 grid of nine equal areas. The door wall is the front row, so the door always falls in Knowledge, Career or Helpful People . The far-left corner is Wealth , the far-right Relationships . Classical schools lay the same nine areas by compass instead, with Career to the north. In a 3 × 3.5 m bedroom each area is 100 × 117 cm. https://snuug.app/tools/curtain-size https://snuug.app/tools/curtain-size Sun, 01 Nov 2026 09:00:00 GMT Tools Measure the pole, not the window . The pole runs 15–20 cm past each side of the window and sits at least 15 cm above it . For the standard gather, buy a pair where each curtain is about as wide as the pole : UK ready-made curtains come 117, 168 or 229 cm wide (46, 66, 90 in) and 137, 183 or 229 cm long (54, 72, 90 in). A 120 cm window takes a 160 cm pole and a 168 × 229 cm pair to the floor, with the pole's top at 230 cm. https://snuug.app/tools/dining-table https://snuug.app/tools/dining-table Sun, 01 Nov 2026 09:00:00 GMT Tools Give each person 60 cm of table edge , and leave about 90 cm from the table edge to the wall so someone can edge past a seated diner (91 cm in the NKBA's guidelines; 75 cm is the least for a chair to pull out). A table for 4 is about 120 × 80 cm or 90–110 cm round; for 6, 150–180 × 90 cm or 135 cm round; for 8, 200–220 × 100 cm or 180 cm round. For the room, add about 180 cm to the table's length and to its width. https://snuug.app/tools/home-size https://snuug.app/tools/home-size Sun, 01 Nov 2026 09:00:00 GMT Tools England's nationally described space standard asks a new home for at least 39 m² for one person , 50 m² for a one-bedroom flat for two , 70 m² for a two-bedroom flat for four and 93 m² for a three-bedroom house for five . A single bedroom is at least 7.5 m², a double 11.5 m². The average home in England is 94 m². The standard is a planning rule for new homes, not a law for the home you live in now. https://snuug.app/tools/kua-number https://snuug.app/tools/kua-number Sun, 01 Nov 2026 09:00:00 GMT Tools In feng shui's Eight Mansions school, the tradition holds that your kua number (1 to 9, never 5) comes from your birth year, with one formula for men and one for women. Add the year's digits down to one digit (s): the male formula is 11 − s , the female 4 + s , each reduced to one digit. Kua 1, 3, 4 and 9 are the East group (favourable directions N, S, E, SE); 2, 6, 7 and 8 the West group (W, NW, SW, NE). The year starts at Li Chun, about 4 February. https://snuug.app/tools/lighting https://snuug.app/tools/lighting Sun, 01 Nov 2026 09:00:00 GMT Tools Plan on about 200–400 lumens per square metre of floor for a living room with light walls: that gives the 100–200 lux UK lighting guidance suggests, once you allow for the light that walls and shades take in. An 18 m² living room needs about 3,600–7,200 lm in all: five to nine 806 lm (60 W) bulbs, spread over the ceiling and lamps. A kitchen needs about 325–650 lm per m², a bedroom 110–220. Space downlights about half the ceiling height apart : 1.2 m under a 2.4 m ceiling, 60 cm from the walls. https://snuug.app/tools/paint https://snuug.app/tools/paint Sun, 01 Nov 2026 09:00:00 GMT Tools Measure round the room, multiply by the height, and take off about 1.5 m² for each door and 1.4 m² for each window. Multiply by two coats and divide by 13 m² per litre , the figure Dulux gives for its matt and silk emulsion. A 4 × 3 m room with 2.4 m ceilings has about 30.7 m² of wall, so it needs 4.7 litres : one 5 l tin, or a 5 l and a 2.5 l if you want 10% spare. https://snuug.app/tools/pendant-light https://snuug.app/tools/pendant-light Sun, 01 Nov 2026 09:00:00 GMT Tools Hang the bottom of the light 75–90 cm above the table (30–36 in) under a 2.4 m ceiling, and about 7.5 cm higher for every 30 cm of extra ceiling. Make it half to two thirds of the table's width : 45–60 cm across over a 90 cm table. Where people walk under it, keep the bottom at least 2.1 m from the floor . For a light in the middle of a room, add the room's length and width in feet: the sum in inches is the diameter. https://snuug.app/tools/picture-height https://snuug.app/tools/picture-height Sun, 01 Nov 2026 09:00:00 GMT Tools On an open wall, hang a picture so its centre is 145–150 cm from the floor (57–60 in). Over a sofa or sideboard, leave 15–25 cm between the furniture and the frame, and make the art about two thirds of the furniture's width . The hook goes at the centre height, plus half the frame's height, minus the hanger drop. https://snuug.app/tools/room-size https://snuug.app/tools/room-size Sun, 01 Nov 2026 09:00:00 GMT Tools Multiply the length by the width. A 3 × 4 m room is 12 m² (129 sq ft), and a 12 × 12 ft room is 144 sq ft (13.4 m²). To convert, 1 m² = 10.764 sq ft and 1 sq ft = 0.0929 m². Split an L-shaped room into two rectangles and add them. For scale, England's space standard counts a double bedroom from 11.5 m², and the average living room in a home built since 2010 is 17.1 m². https://snuug.app/tools/rug-size https://snuug.app/tools/rug-size Sun, 01 Nov 2026 09:00:00 GMT Tools Choose a rug that runs 15–20 cm past each end of the sofa and reaches under its front legs, with 30–45 cm of floor left to the walls. For a 2–2.6 m sofa that is a 200 × 290 cm rug (about 6 × 9 ft). A 160 × 230 cm rug suits a sofa up to 2 m; a 240 × 340 cm rug lets every leg stand on it. https://snuug.app/tools/sofa-fit https://snuug.app/tools/sofa-fit Sun, 01 Nov 2026 09:00:00 GMT Tools A sofa goes through a door if its depth or height, whichever is smaller, is less than the door's clear width . If not, it can be tipped back through when its diagonal depth is less than the clear width. Its length then has to turn: under the door height to stand it on end, or under the hall width to swing it round. A standard UK internal door is 762 mm wide but leaves only about 70–72 cm clear. https://snuug.app/tools/tv-height-distance https://snuug.app/tools/tv-height-distance Sun, 01 Nov 2026 09:00:00 GMT Tools Mount the TV so the centre of the screen is at your seated eye height : about 100–110 cm from the floor on most sofas, but measure yours. Sit 1.2 to 1.6 times the screen's diagonal away: 1.7–2.3 m for a 55-inch TV (THX 40° to SMPTE 30°). Keep the top edge within 15° of your eye line, as CEDIA recommends. https://snuug.app/tools/wallpaper https://snuug.app/tools/wallpaper Sun, 01 Nov 2026 09:00:00 GMT Tools Divide the width of your walls by the roll's width (53 cm) to get the number of drops , the strips you hang. Divide the roll's length (10.05 m) by the wall height plus 10 cm, and round down, to get drops per roll . Divide the first by the second and round up. A 4 × 3 m room with 2.4 m walls needs 7 rolls of plain paper, or 9 with a 53 cm straight-match pattern. Buy one more with the same batch number.
