Can a pothos live in a dark corner?

It depends what the corner reads. A corner four metres from any window, around 125 lux, scores 63 and the plant holds there without growing much. The dark corner we measured in a real living room was 18 lux, and nothing holds at that level.

Can a pothos sit on a sunny windowsill?

Every sill with direct sun in our table is flagged, and the south one is refused outright at 45. Three metres back from that same south window the plant scores 100. The window is fine; the sill is the part that is too bright.

Are pothos plants safe for cats?

No. The ASPCA lists pothos as toxic to cats and dogs because of the calcium oxalates in the leaves. The usual result is a sore mouth and drooling rather than anything dangerous, but the vine still belongs out of reach.

How Much Light a Pothos Needs, in Lux

Q: How many lux does a pothos need?

In our scoring a golden pothos is ideal from roughly 400 lux to around 5,000 lux. Below that it holds rather than grows, and above it the plant is flagged for too much light. A south sill on a clear day reads about 13,000 lux and scores 45 out of 100.

Scored with our own care data, a golden pothos does best between 400 and 5,000 lux. Every spot from 1,111 lux three metres inside a north window to 5,000 lux a metre from an east window scores 99 or 100. The three sunny sills are the ones that fail: a south sill at 13,000 lux scores 45, a west sill at 7,800 scores 66, an east sill at 6,500 scores 67.

People search for this in lux because the qualitative answer has stopped helping. “Tolerates low light, bright indirect is best” is printed on the pothos label and on the labels of most of the plants next to it, so it cannot tell you whether the shelf you have in mind is one of the good ones or the one that scores 45.

How many lux does a pothos need?

Before our own scoring says anything: we gathered every published figure we could find for a pothos. 6 of them, from 5 separate sources, in 3 different units. They are reproduced below exactly as each source writes them, and nothing here is converted.

Who publishes it	What it says a pothos needs	What the figure is
theplantrunner.com	800–2,000+ lux	Standard foliage plants (pothos, Philodendron, Monstera deliciosa …) — a general band, not a single-species figure
houseplantjournal.com	100 foot-candles	Pothos — minimum indirect light
houseplantjournal.com	200 foot-candles	Pothos — good indirect light
growlightmeter.com	5 – 10 PPFD / DLI	Pothos
extension.arizona.edu	25–75 foot-candles	listed under the heading "Low Light (25–75 fc)"
houseplantsnook.com	50–100 foot-candles	chart fc level

Every published figure we could find for a pothos, one row per source, in the unit each one uses. They came out of a corpus of 433 light figures gathered from 34 sources across ten separate populations, and they were not selected for agreement. 6 figures transcribed from 5 sources, read end to end on 29 August 2026. Units are copied exactly as each source writes them; nothing here is converted, and nothing here is our own measurement. All of them, from every page, are one free download.

A golden pothos trailing from a high shelf in the corner of a room, its vines hanging down a tiled wall, with no window in shot — A pothos in the corner of a room, the spot every guide says it tolerates. The published ranges agree it will live there; none of them say how much of the room counts as the corner.

In our care data a pothos sits in the low-light category, and in scoring it comes out ideal from roughly 400 lux up to around 5,000 lux. Below that it is still alive but flagged, and above it the flag comes back from the other side. The upper flag is the half nobody prints on the label, and it is the half that decides the sunny sill.

Nine spots, scored

These are all indoor spots at typical clear-day conditions, with temperature, humidity and airflow set to the plant’s own preferences so that the only thing changing between rows is light.

Every row, one plant each (9)

Spot	Estimated light	What the light is doing	Verdict
South sill, against the glass	13,000 lux	Too bright here	Not the best fit right now, 45/100
West sill	7,800 lux	A bit bright, but workable	Worth a try, 66/100
East sill	6,500 lux	A bit bright, but workable	Worth a try, 67/100
1 m in from an east window	5,000 lux	Just the right amount of light	Great fit, 99/100
3 m in from an east window	1,984 lux	Just the right amount of light	Great fit, 100/100
North sill	3,640 lux	Just the right amount of light	Great fit, 100/100
2 m in from a north window	1,764 lux	Just the right amount of light	Great fit, 100/100
3 m in from a north window	1,111 lux	Just the right amount of light	Great fit, 100/100
A corner 4 m from any window	125 lux	A little dim, but workable	Worth a try, 63/100

Nine indoor spots at typical clear-day conditions, scored for the same golden pothos. The spot is what moves here. What does not: the same plant, the same home on the same clear day, with 22 °C, 50% humidity and medium airflow on every row. The middle column is only what the light is doing. The verdict is the whole spot, so a plant can have the light it wants and still lose points on warmth, humidity or airflow.

Read the verdict column and the room splits cleanly in two. The three sills with direct sun are the three spots below 70, and the south one is the only row in the table the scoring refuses outright. Everything else is 99 or 100, right down to a metre inside a north window at 1,111 lux. The one exception at the dim end is the corner four metres from any glass, at 125 lux, which comes back as worth a try at 63.

That is a different shape from the snake plant table, which shares the low-light band. The snake plant is only flagged on the south sill, at 66. The pothos is refused there. Same band, same house, same clear day, and the plant with the softer leaf takes the harder penalty at the glass.

Walking it back from a south window

The south sill is the spot people move a pothos to when it looks tired, so it is worth following that one window all the way in, half a metre at a time and then a metre at a time.

Distance from the window	Estimated light	Verdict
0.3 m, against the glass	13,000 lux	Not the best fit right now, 45/100
1 m back	10,000 lux	Worth a try, 63/100
2 m back	6,300 lux	Worth a try, 68/100
3 m back	3,969 lux	Great fit, 100/100
4 m back	2,500 lux	Great fit, 100/100
5 m back	1,575 lux	Great fit, 100/100

Walking a pothos back from a south window, half a metre at a time. The spot is what moves here. What does not: the same plant, a south-facing window, with 22 °C, 50% humidity and medium airflow on every row.

The line falls between two and three metres. At the glass the plant is refused at 45; a metre back it is worth a try at 63; two metres back, still under the direct beam at 6,300 lux, it is 68. At three metres, 3,969 lux, it is 100, and it stays 100 at four and five. A south window is a fine place for a pothos. The sill is the one part of it that is not.

The east-window page walks the gentler window the same way, and the west-window page follows the afternoon one. The answer on both is a metre or two shorter than the south walk, because there is less light to walk away from.

What that means for the plant that lives anywhere

A variegated pothos in a hanging pot in front of a bright window, its white-and-green leaves lit from behind, one leaf marked brown — A variegated pothos hung right in a bright window. The variegation is the tell: the white halves of those leaves make no food, so this plant is the one pothos that has a reason to be this close to the glass.

“It tolerates low light” is true, and tolerating is doing a lot of work in that sentence. A corner at 125 lux scores 63, which the scoring calls worth a try, and in practice that means the plant holds. The vines stop lengthening, the new leaves come in smaller, and a year in that corner looks almost identical to the day it arrived. That is a legitimate way to keep a pothos. It is not the trailing curtain of leaves on the shop poster, which was grown somewhere between 1,000 and 5,000 lux.

“It lives anywhere” is the half that is wrong, and it is wrong at the bright end. Nine spots, three sills, three flags, one refusal. A shade-adapted leaf moved in one step from a shelf at 500 lux to a sill at 13,000 is the usual way a pothos gets scorched, and the scoring is saying so before the leaf does. The variegated forms are the exception worth naming: the white parts of a marble queen make no food, so that plant is the one pothos with a reason to sit closer to the glass than the golden form in these tables.

What do 400 and 5,000 lux look like in a real room?

Numbers like 400 and 5,000 mean very little until you have stood somewhere and know what they feel like, which is the problem, because they do not feel like anything. So here are six places in one ordinary living room, read on a clear day:

The built-in light meter in the GrowSpot app reading 8,400 lux at a spot and calling it bright, indirect — Every figure in the tables above is estimated from a window and a distance. This reads the spot instead of inferring it: lay the phone down where the pot goes, and the number belongs to that shelf rather than to a shelf like it.

Spot	Reading
At the bright window	20,000 lux
1 m from the window	15,000 lux
2–3 m away, in window shade	3,500 lux
Middle of the room	570 lux
Darker side of the room	119 lux
The dark corner	18 lux

One living room, six spots, read inside the same hour. How this was measured → The full indoor light dataset →

Line that up against the tables. The bright window at 20,000 lux and the spot a metre from it at 15,000 are both past the top of the pothos band, further past it than the south sill in the table. The middle of that room, at 570 lux, is inside the band. The darker side at 119 lux is the corner row, holding. The dark corner at 18 lux is where nothing holds, and the 570 and the 18 both come from the same measured room.

Why the published numbers disagree with each other

Search this and you will find the pothos filed under low light by two sources and under a general foliage band starting at 800 lux by a third, with the two ends of that spread not overlapping at all. Our own scoring calls 400 lux ideal and 6,500 flagged, which sits inside the low-light filing at one end and inside the foliage band at the other.

Both can be defended, because they answer different questions: a floor is where the plant stops losing leaves, a growth band sits higher. Neither can tell you whether your shelf clears the bar, and that is the only question that changes what you do next. The same table built for a fiddle leaf fig is the mirror image of this one: the three sills the pothos fails are the only three spots the fig passes.

Published advice is written in tiers while a room is written in numbers; the four tiers with a box to type your own reading into is the general version of this page. The peace lily shares the band and fails the sunny sill the same way, with one extra flag a metre from an east window.

Is pothos safe for cats?

Pothos is listed by the ASPCA as toxic to cats and dogs, because of the insoluble calcium oxalates in the leaves. The usual result of a chewed leaf is a sore mouth and drooling rather than anything dangerous, and it is still worth knowing before a trailing vine goes somewhere a cat can bat at it. This is the one fact on this page that does not depend on your spot at all.
