Scored at 21 °C and 45% humidity, a jade plant on an east sill gets about 6,500 lux and comes back 59 out of 100, worth a try, with the light marked a little dim. At 0.6 m from the glass it still holds at 58. At 0.7 m it drops to 41, and nowhere further back does it climb above that.
Read on 14 October 2026, the top results can’t agree on whether this window works at all. Lively Root says to keep a jade out of north- and east-facing windows for lack of light. Petal Republic calls an east or south sill the perfect spot. Your Indoor Plant calls east the most forgiving placement and puts the pot within one to two feet of the glass, year-round. Simplify Plants is the one that warns east stops being enough in winter, when the light is weak. The pages that put a number on it count hours, mostly four to six. None of them gives a light level.
Scored, the sill lands between those verdicts, and the one-to-two-feet range turns out to be all the room there is. “Year-round” is the claim that fails.

Is an east-facing window enough light for a jade plant?
The figures other people publish for a jade come first, copied the way each source prints them:
| Who publishes it | What it says a jade plant needs | What the figure is |
|---|---|---|
| extension.arizona.edu | 150–1000 foot-candles | listed under the heading "High Light (150–1000 fc)" |
| houseplantjournal.com | 200 FC (40 µmol) foot-candles | minimum indirect light level |
| houseplantjournal.com | 400 FC (80 µmol) foot-candles | good indirect light level |
| houseplantsnook.com | 400–800 foot-candles | chart fc level |
Barely, and only right at the glass. On the sill the estimate is 6,500 lux, and the card reads the light there as a little dim, but workable, which is as far as a jade gets at this window. Temperature sits in its band. Humidity and airflow each cost a point or two; drier air and a little more air movement would lift the sill a few points and still leave it worth a try.
So light decides this window, and the sill has just enough of it. The north-window page lines up all four sills for this plant. None of them reaches a good fit; east sits a point under west and a few under south.
The jade light page scores nine indoor spots and finds none where the light reads right for this plant. A jade wants more than most windows give, and an east sill gives a little less than a south or west one.
How far from an east window can a jade plant go?
About 60 cm. Here is the same plant moved back from the glass, in short steps where the answer changes:
| Distance from the glass | Estimated light | What the light is doing | Verdict |
|---|---|---|---|
| 0.3 m, against the glass | 6,500 lux | A little dim, but workable | Worth a try, 59/100 |
| 0.5 m back | 6,300 lux | A little dim, but workable | Worth a try, 58/100 |
| 0.6 m back | 6,015 lux | A little dim, but workable | Worth a try, 58/100 |
| 0.7 m back | 5,743 lux | Too dim here | Not the best fit right now, 41/100 |
| 1 m back | 5,000 lux | Too dim here | Not the best fit right now, 41/100 |
| 3 m back | 1,984 lux | Too dim here | Not the best fit right now, 39/100 |
Between 0.6 m and 0.7 m the estimate slips from 6,015 to 5,743 lux, the light column turns from a little dim to too dim, and the score goes from 58 to 41. A metre back reads 41, three metres 39. Once the pot is past that step, a metre and three metres give the same answer.
Hold Your Indoor Plant’s range up against that. One foot is the sill row. Two feet lands on the 0.6 m row, the last one before the drop. So the range is right, with nothing to spare: a plant stand one pace back from the sill is already out of it.
A ZZ plant at the same east window changes verdict across the same ten centimetres, the other way round. The sill reads a bit bright for it, and 0.7 m is where it settles.
Does an east sill still work for a jade in winter?
No. Here is the sill from the card, scored on the 21st of six months at latitude 40 degrees, near New York or Beijing:
| The month on the sill | Estimated light | What the light is doing | Verdict |
|---|---|---|---|
| February | 5,314 lux | Too dim here | Not the best fit right now, 41/100 |
| March | 6,461 lux | A little dim, but workable | Worth a try, 59/100 |
| June | 7,800 lux | A little dim, but workable | Worth a try, 60/100 |
| September | 6,481 lux | A little dim, but workable | Worth a try, 59/100 |
| October | 5,253 lux | Too dim here | Not the best fit right now, 41/100 |
| December | 3,793 lux | Too dim here | Not the best fit right now, 40/100 |
March, June and September read 59 or 60. February and October read 41, and December 40. The sill gets 7,800 lux in June and 3,793 in December, and by then it scores the same 40 a north sill does.
We ran the same sill at 35, 45 and 52 degrees too. At all four latitudes it drops out around the start of October and comes back by the middle of March. On 14 October, the day this page went up, it was under at every one.
That is where Simplify Plants’ warning holds and “year-round” doesn’t. In June the workable strip runs about a metre deep. In December there isn’t one.
If you have a south sill, winter is the time to borrow it: at latitude 40 in December it’s the one sill of the four still reading worth a try. The south-window page walks a jade back from that glass, and it stays worth a try further into the room than anything here.
Is bright, indirect light enough for a jade plant?
Not as a label. The app’s light meter shows why:
That word covers everything from 2,500 lux to just under 10,000. On the distance table it takes in the sill at 6,500, which passes for a jade, and the spot a metre back at 5,000, which doesn’t. Only at three metres, at 1,984, would the meter change its word. Flora asks for bright, indirect sunlight four to six hours a day; an east room meets that wording where this plant scores 41.
What if something shades the window in the morning?
Every lux figure here is an estimate from the window’s direction, the distance and a clear day, not a meter reading. Your own edge will differ. What carries over is how little margin the sill has.
Moving from the sill to 0.7 m costs the reading a little over a tenth of its light, and that is enough to flip the verdict. A tree or the building across the street only has to take the same tenth off the morning to do that to the sill itself.
The east window guide sorts out which plants go at the glass and which further in. For your own sill, the free spot checker scores it with live weather where you live.
