BlogThe 100 cmLeaf Project
One indoor-grown Monstera sp. ‘Esqueleto’. One documented attempt to grow a fully hardened leaf beyond one metre.
Open the field record
The next record is already in view.
Leaf 29 has added 35 cm, or 66.0%, since its 53 cm closed-stage measurement. At 88 × 49 cm it already matches Leaf 27's former mature record and sits just 1 cm shorter and 1 cm narrower than Leaf 28's final measurement, making it likely to become the next record leaf.
Leaves 28 and 29 developed under significantly less light than Leaves 20–27 while an alternative lighting solution is still being evaluated. Reduced light is a plausible contributor—not a proven sole cause—to the sharp loss of mature size-up momentum: Leaf 26 to Leaf 27 added 9 cm, while Leaf 27 to Leaf 28 added only 1 cm.

Completed at 89 × 50 cm.
After opening at 77 × 45 cm, Leaf 28 added 12 cm in length (+15.6%) and 5 cm in width (+11.1%). From the 58 cm closed stage to the final 89 cm measurement it expanded by 31 cm, or 53.4%.

So I document the climb.
When this Monstera ‘Esqueleto’ arrived in April 2024, it was a three-leaf cutting with a largest leaf measuring just 15 cm. Two years later, grown indoors in PON in my living room, it has produced an 88 cm leaf.
That raised a simple question: how large can an Esqueleto leaf actually get?
I searched websites, forums, social media and grower groups, spoke to people with mature specimens and even deployed several AI research agents to investigate. Despite all that, I could not find a definitive answer, a recognised record or a properly documented biological maximum.
The Aroid Cultivar Registry describes Monstera ‘Esqueleto’ as producing leaf blades up to 78 cm long and 43 cm wide, a figure my plant has already exceeded. Google’s AI Overview later used my own 77 cm leaf as an example of an “extreme specimen,” although that information was already outdated by the time I found it.
So rather than continue waiting for someone else to establish the limit, I decided to document the attempt myself.
This page follows the journey towards a fully hardened leaf exceeding one metre, recording each new leaf, its measurements, development time and growing conditions along the way. The goal is not simply to grow an enormous leaf, but to create a useful public record for growers, researchers, the aroid community and, apparently, Google.
Ten leaves. One moving limit.
Select a leaf to inspect the measurement. Mature statistics use Leaves 20–28; Leaf 29 is a live reading and remains excluded.

The specimen, frame by frame.
Three routes past one metre.
The central forecast now places the first mature leaf above one metre at Leaf 31. Every route is a provisional planning scenario—not a biological guarantee—and success still means longer than 100 cm after hardening, not a live measurement that merely rounds up.
The central planning case assumes approximately 5% size-up per leaf.
The regular central path puts Leaf 31 first past 100 cm; the best case is Leaf 30 after corrected lighting, and the continued-low-light case is Leaf 34.
A feed engineered for the climb.

A living chorus of reactions from growers, friends and first-time visitors who have met the plant in person.
One record hardened. The next is still moving.
Forecast method note — The projections use the recorded mature dimensions of Leaves 20–28 and a 91 cm central mature estimate for the still-developing Leaf 29. The three paths apply approximately 10%, 5%, or 2.2% size-up per later leaf; fitted widths use the length-to-width relationship across the nine mature leaves. Leaves 28 and 29 developed under significantly less light than Leaves 20–27, but lighting is treated as a caveat rather than a proven sole cause. All scenarios are provisional planning ranges, not biological guarantees, and will be refreshed when Leaf 29 is fully hardened.
