What is the most common form of meter?

The most common form of meter in poetry is iambic pentameter. This meter consists of five iambs per line, where each iamb is a two-syllable unit with the first syllable unstressed and the second stressed (da-DUM). It is widely used in English poetry, notably by William Shakespeare and other classic poets, creating a rhythmic and flowing quality that enhances the emotional resonance of the verse.
