Two sides. Letter or A4. Pick inches or centimeters before you press print, because this sheet prints whatever is on the screen at that moment, and nobody wants to find that out on the second page.

As wide as the sofa, better 6 to 12 in wider each side. It connects the furniture instead of floating between it.
Of bare floor in a large room, 8 to 10 in in a small one. Less floor showing makes a small room read as one space.
Of the sofa length. Proportion, and you can still reach the end cushions.
14 to 18 in of gap. Reach a glass without standing, walk past without a bruise.
Within 1 to 2 in of the seat cushion, either way. Elbows and glasses land where you expect.
1.5 to 2.5 times the screen diagonal; a 55 in screen wants 7 to 11 ft. Any closer and you watch pixels.
To the center of the screen. That is seated eye level, and lower than televisions usually end up.
And 24 in minimum where you squeeze past. Two people pass at 36, one turns sideways at 24.
Center of the piece, 57 to 60 in from the floor; lower where you sit. A starting point between standing and seated eyes.
6 to 8 in above it, two thirds to three quarters of its width. Rules of thumb; close things read as one.
2 to 3 in between frames, group centered at 57 to 60 in, lower over a sofa. Tight spacing reads as one piece.
As close to the ceiling as the bracket allows, never under 4 to 6 in above the frame; brackets 4 to 10 in past it each side. The window reads taller and wider.
Panels add up to 2 to 2.5 times the window width. Fullness. Flat panels look like bedsheets.
Touching it, or half an inch above. A 1 to 3 in puddle if you like it. Floating three inches up looks like a mistake.
Past the table edge on every side, so table plus 48. Chairs stay on the rug when somebody stands up.
And 42 to 48 in to walk behind a seated person. Someone always has to get past.
Of table edge per person, 30 is generous. Elbows. The same 24 doing a different job.
30 to 36 in above the table, half to two thirds of its width across. Light on the food, not in the eyes.
18 to 24 in past the sides and foot, starting below the nightstands. Feet land on something soft.
With the top of the mattress, give or take 2 in. You reach for the glass without looking.
Shade bottom at chin height sitting up, lamp about as tall as the nightstand. Dim it the last hour before sleep.
Minimum each side you get out of, 30 to 36 in is comfortable. Making the bed needs the space too.
Shade bottom at or just below seated eye level; side table within 2 in of the arm. If you can see the bulb, it is too high.
20 to 22 in, 24 in on a deep sectional. Big to small, back to front. Scale to the seat depth.
24 to 26 in for a 36 in counter, 28 to 30 in for a 42 in bar. Knees fit, elbows do not touch.
60 to 66 in, second row 40 to 48 in, console under 15 in deep. Coats clear the floor and you get past.
Your walls are the 60. The 10 is something chair-sized; pillows only echo it.
Or dimmable 2200 to 3000K for evenings; 3000 to 4000K kitchens and baths; 4000K+ for desk work. For faces, CRI 90+. At night, dimmer beats warmer.
Bulb lumens: 10 to 20 in a living room, 20 to 40 in a kitchen. Plus a reading light and under-cabinet light.
Ambient, task, accent: three sources at three heights. Softer shadows, light on the walls.
