How Much Light a Fiddle Leaf Fig Needs, in Lux

Scored across nine real spots, it is ideal from 6,500 lux up, and only three of nine ordinary spots get there. All three are sills with direct sun. The north sill scores 65, a metre in from an east window scores 67, and the middle of the room is not a fit at all.

Ideal from 6,500 luxThree metres from south glass: 66Toxic to cats and dogs

Scored with our own care data, a fiddle leaf fig does best from about 6,500 lux upward. On a clear day that is a south sill at 13,000 lux, a west sill at 7,800, or an east sill at 6,500, and those sills score 100, 99 and 98.

Everything else in the nine-spot table is flagged. The north sill at 3,640 lux scores 65, and three metres inside an east window, at 1,984 lux, the plant is refused at 47.

This is the plant people search for in lux because it is the plant they have already lost once. The label says bright indirect light, the same words that are on the pothos next to it, and the two plants want rooms that barely overlap. A number tells them apart. The words do not.

How many lux does a fiddle leaf fig need?

Before our own scoring says anything: we gathered every published figure we could find for a fiddle leaf fig. 7 of them, from 5 separate sources. They are reproduced below exactly as each source writes them, and nothing here is converted.

Every published figure we could find for a fiddle leaf fig, 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. 7 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 new leaf unfurling at a bright window. The paler, red-veined leaf is the sign the plant has light to spare; the rows below are what happens to that leaf three metres further in.

In our care data a fiddle leaf fig sits in the high-light category, and in scoring it comes out ideal from roughly 6,500 lux up to somewhere past 13,000. Below 6,500 it is flagged as dim, and below about 2,000 it is refused. There is an upper edge too, but it is not indoors: the balcony table further down finds it.

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.

Nine indoor spots at typical clear-day conditions, scored for the same fiddle leaf fig. 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 light 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 shape is the opposite of every other species page on this site. Three rows pass, and they are the three sills with direct sun. Two rows are worth a try: the north sill at 65 and a metre inside the east window at 67. The other four are refused, and they include the spots a pothos or a peace lily would call perfect, two and three metres inside a north window at 47 and 46.

Set this next to the pothos table and the two plants trade places almost row for row. The south sill that refuses the pothos at 45 is the fig’s 100. The spot three metres inside the north window, where the pothos scores 100, is the fig’s 46. Same house, same clear day, and the one instruction printed on both labels is the one that fits neither of them.

The cliff between two and three metres

A south window is the fig’s best window, so here it is followed all the way in, half a metre at a time and then a metre at a time.

Walking a fiddle leaf fig back from a south window, one 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 light airflow on every row.

The first two metres are the plant’s whole comfortable zone: 100 at the glass, 100 a metre back, 98 at two metres and 6,300 lux. Then it drops. Three metres back, at 3,969 lux, is 66, four metres is 63, and five metres, at 1,575 lux, is refused at 47. The difference between two metres and three is a foot or two of floor and 32 points. That is the cliff, and it is why a fiddle leaf fig that was fine by the window drops leaves when it is moved across the room to where it looks better.

The south-window page follows this same window with the temperature and humidity of a real room, and the north-window page shows the window where the cliff starts at the glass.

What about the balcony?

A plant that scores 100 at 13,000 lux sounds like a plant with no ceiling, so it is worth checking the sunnier direction. Run the same fig through the same scoring on a south-facing balcony, at 45,000 lux, and it is back to worth a try, at 62. In the open, at 80,000 lux, it is refused at 42. So the window is the fig’s spot, and the window is not a step towards the garden. The plant wants the brightest place indoors, and indoors is the key word in that sentence.

What does 6,500 lux look like in a real room?

Numbers like 6,500 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:

Line that up against the tables and this room has exactly two spots for a fiddle leaf fig: the window at 20,000 lux and the spot a metre from it at 15,000.

The spot two to three metres in, at 3,500 lux, is already below the band and matches the three-metre row of the south walk. The middle of the room at 570 lux is where the fig gets refused. The 3,500 and the 570 both come from the same measured room, and it is a bright room by most standards.

Why the published numbers disagree with each other

Search this and you will find one botanic garden publishing a floor and a target for the same plant, the target eight times the floor. Another source gives a foliage band from 1,500 lux, and an extension service files the plant under medium light. Our own scoring turns green at about 6,500 lux, above every floor in the table and inside the highest band.

They can all be defended, because a floor and a comfortable band are different questions. The floor is where the leaves start to drop; the band is where the plant is comfortable, and a fiddle leaf fig can sit well above its floor and still lose leaves slowly for a year. None of the published figures 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 jade plant has the same shape and a lower cliff, and the peace lily is the mirror.

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.

Are fiddle leaf figs safe for cats?

The fiddle leaf fig is listed by the ASPCA as toxic to cats and dogs. The sap irritates the mouth and the skin, and a chewed leaf usually means drooling and a sore mouth rather than anything dangerous. It is still worth knowing before a floor-standing tree goes in a house with a chewer, because the lowest leaves are at exactly the wrong height. This is the one fact on this page that does not depend on your spot at all.

Questions, answered honestly

How many lux does a fiddle leaf fig need?

In our scoring a fiddle leaf fig is ideal from roughly 6,500 lux upward. Below that it is flagged as dim, and below about 2,000 lux it is refused. On a clear day that means the sill of a south, west or east window; a north sill at 3,640 lux scores 65 out of 100.

Can a fiddle leaf fig survive in low light?

Not comfortably. Three metres inside a north window, around 1,111 lux, scores 46 and the plant is refused. The middle of the room we measured, at 570 lux, is below anything in the fig’s band. It will hold for a while and drop leaves slowly, which is the usual story.

How far from a south window can a fiddle leaf fig be?

About two metres. In our south-window walk the plant scores 100 at the glass, 100 a metre back and 98 at two metres, then 66 at three and 47 at five. The cliff between two and three metres is 32 points.

Are fiddle leaf figs safe for cats?

No. The ASPCA lists the fiddle leaf fig as toxic to cats and dogs. The sap irritates the mouth and skin, so the result is usually drooling and a sore mouth rather than anything dangerous, but the lowest leaves still belong out of reach.
