Mona Lisa reproduction: you are copying the varnish, not the painting

The Louvre says oxidised varnish now filters the Mona Lisa yellow and turns its sky green. Every copy reproduces that filter. Sizes, prices, what to ask.

Leonardo da Vinci's Mona Lisa: a seated woman with folded hands in front of a hazy blue-green landscape. — Leonardo da Vinci, *Mona Lisa (La Gioconda)*, c. 1503–1519. Oil on poplar panel, 79.4 × 53.4 cm. Musee du Louvre, Paris, INV 779. Wikimedia Commons, public domain

The short answer

The Louvre records the panel as 79.4 × 53.4 cm of oil on poplar, under thick oxidised varnish applied after Leonardo died. That varnish is why the sky reads green and the picture reads brown. Reproductions copy it as if it were paint.

The painting in numbers

What a copyist is actually working from.

	The original	What it means for a reproduction
Year	About 1503–1519	Leonardo died in 1519; the image is public domain everywhere.
Where it is	Musee du Louvre, Paris, INV 779	The Louvre publishes its own condition notes, which contradict most store descriptions.
Medium	Oil on a thin poplar panel, not canvas	No reproduction on canvas has the same support, so the surface is different before a brush is loaded.
Original size	79.4 × 53.4 cm (31.3 × 21 in)	Narrower than any common stock canvas of the same height.
Aspect ratio	1.49 : 1, portrait	No standard size matches. 30 × 24 in is 1.25:1 and 40 × 30 in is 1.33:1, so both are wider than the panel.
Condition	Varnish layers added after Leonardo's death have oxidised into a yellow filter; a crack about 11 cm long runs down from the top of the panel	The colours you know are aged colours. The crack is damage and should never be reproduced.

Why it is hard to reproduce

Leonardo built the face out of glazes: layers of oil barely loaded with pigment, each dried before the next, so that the transition from light to shadow has no edge anywhere. That is what sfumato means in practice, and it is a schedule problem as much as a skill problem. A studio that has two weeks cannot dry six glazes, so it paints the effect opaquely in one pass, and the softness becomes a blur instead of a depth.

There is no edge at the corner of the mouth or the eye, only a graded shadow; the fine crack network and the yellow cast both belong to the panel's age, not to Leonardo's palette.

You are copying a filter. The Louvre's record, published in French, says that varnish layers applied after the artist's death, thick and uneven and now oxidised, form a yellow filter that has turned the blue of the sky green and darkened the lower part of the picture. That is a translation of the museum's own wording, not an inference. A copyist matching the photograph is matching that filter with opaque paint.
Panel, not canvas. Poplar takes a glaze differently from woven linen, and it does not show a weave. Any reproduction on canvas has a texture the original does not.
No hard edges at all. Sharpen the corner of the mouth by half a millimetre and the expression changes. This is the painting where the myth of the ambiguous smile is a technical fact about edge quality.
A 1.49:1 format. Every common stock size is wider. The studio either adds landscape at the sides or crops the top and the hands, and most do not say which.

What cheap copies get wrong

The commonest fault is a brown picture. Copying the yellowed photograph in opaque paint bakes the varnish into the pigment, so the copy starts where the original will be in another century, and it has nowhere to go. The better studios lift the value slightly and keep the sky blue, and say so.

The whole picture mixed toward brown, because the reference photograph is yellow.
Hard edges at the eyes and mouth, which replace the expression with a smirk.
Craquelure imitated with crackle varnish. The Louvre's crack networks come from a warped panel; a canvas cannot crack that way and the imitation always looks regular.
The 11 cm split at the top of the panel copied as if it were part of the image.
The background landscape simplified into brown-green mud, losing the atmospheric recession that is half of Leonardo's point.

Sizes and where it hangs well

At 79 × 53 cm this is a domestic-scale portrait, and it behaves like one: it works at eye level on a narrow wall, in a hallway, or above a desk, and it looks absurd blown up to 48 in over a sofa, where the head becomes twice life size. If you want it near the original's proportion, order 30 × 20 in as a custom size rather than accepting a 1.25:1 canvas; if a stock size is the only option, 30 × 24 in adds a little landscape at the sides rather than cutting the hands.

Price range

The five common wall sizes for this subject, unframed, USD. Art & See's ladder has two larger rungs above these.

Size	Art & See list price	Ratio vs the panel's 1.49:1	Note
20 × 16 in (51 × 41 cm)	$299.95	1.25:1, wider	Two thirds of the panel's height.
24 × 20 in (61 × 51 cm)	$359.95	1.2:1, much wider	Adds the most invented landscape.
30 × 24 in (76 × 61 cm)	$430.95	1.25:1, wider	Closest in height to the original.
40 × 30 in (102 × 76 cm)	$529.95	1.33:1	Head noticeably larger than life.
48 × 36 in (122 × 91 cm)	$599.95	1.33:1	Head about twice life size.

Art & See prices from its published unframed rectangular ladder, verified 2026-09-05; two rungs continue past this table, $769.95 at 60 × 40 in and $1,299.95 at 72 × 48 in. Across eight stores surveyed the same day, comparable hand-painted canvases of famous subjects ran from about $150 to about $1,120, and TOPofART was the only one selling at exact museum dimensions.

Art & See lists the Mona Lisa as a vertical painting on the same rectangular ladder it applies to every other painting in its catalogue, from $299.95 at 20 × 16 in. As with every store checked, none of the stock sizes reproduces the panel's 1.49:1 proportion, so ask what happens to the extra width before you buy.

Where to buy

Three routes for the most-copied painting in the world.

Published prices on a seven-rung ladder, from $299.95 at 20 × 16 in to $1,299.95 at 72 × 48 in, and a photograph of the finished canvas before dispatch, which is when to raise the varnish question rather than after delivery.

Art & See

overstockArt — Cheapest of the stores surveyed and carries the Mona Lisa in its best-seller range; a sensible choice if the picture is decorative rather than a study piece.
Louvre collections — The museum's own record, with the condition notes on varnish and the panel crack, is free and tells you more about what you are copying than any store page.

Copyright: what you can and cannot do

Leonardo da Vinci died in 1519, so the painting has been in the public domain for centuries and there is no restriction on copying, selling or displaying a hand-painted version. French law protects the Louvre's own photographs and its name; a copy sold with a claim of museum endorsement is a trade-mark problem, not a copyright one.

Frequently asked questions

Why is the Mona Lisa so yellow?

Because of varnish, not paint. The Louvre's French-language record says that thick, uneven, oxidised varnish layers applied after Leonardo's death now form a yellow filter that turned the sky's blue to green and darkened the lower part of the picture.

What size should I order?

The panel is 79.4 × 53.4 cm, or about 31 × 21 in, a 1.49:1 proportion no standard canvas matches. A custom 30 × 20 in is the closest; among stock sizes, 30 × 24 in keeps the height and widens the landscape rather than cropping the hands.

Should the copy include the cracks?

No. The crack network and the 11 cm split at the top of the panel are damage from a warped piece of poplar. Reproducing them on stretched canvas is imitating an injury the support cannot even sustain.
