Maximum Size Torah Scroll?

[Esrog]

I'm curious to know, how big can a Torah scroll get? Is there a maximum size to a Torah scroll? How long (how high) are the longest Torah scrolls?

[Daniel]

As big as the world.

The world, the entire universe is a Torah scroll - no more. A Torah scroll contains the history of the world, the creation and early history, and the most important things in the world are in it.
Without Torah, the universe wouldn't exist. And without a universe, there would be no Torah; there would be only ha-Kadosh Baruch Hu, He alone.

The world is a huge Torah scroll. It's all around you. Everywhere. Torah is everything; because G-d is everything. G-d is everything; everywhere. The world is G-d, it is Torah. The ground that you walk on was created by Him, and the air you breathe. Torah is everywhere and everything.

Well, that's my 'higher' interpretation anyway.

To answer your question in a more down-to-earth way: I don't know.

Mazel tov!

Of course, only some see the Torah in everything.

What's the actual maximum size? There is, for instance, a maximum size to a halachically valid Chanukah menorah. Is there a maximum size to a Torah scroll?
