How to keep begonia 'cowardly lion' smaller

You are not stuck with the maximum size. For begonia 'cowardly lion' specifically, these are the levers, in order of impact:

Trim the longest vines back to the length you want — begonia 'cowardly lion' takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
Expect to tidy it every few weeks in summer — this is a fast vine that will sprawl if left.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of begonia 'cowardly lion' should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow begonia 'cowardly lion' bigger or faster

Light is almost always the ceiling. The begonia 'cowardly lion' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When begonia 'cowardly lion' outgrows the room (or the pot)

Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.
