In architecture, it means the spacing between columns that supports an arch or an entablature , as measured at the bottom of their shafts.

Intercolumniation was determined from a system codified by the 1st-century BC Roman architect Vitruvius.

Vitruvius, in full Marcus Vitruvius Pollio , Roman architect, engineer, and author of the celebrated treatise De architectura (On Architecture), a handbook for Roman architects.

 

Vitruvius established five standard measurements for intercolumniation:


Pycnostyle

One and a half diameters

Systyle

Two diameters

Eustyle

Two and a quarter diameters, considered by Vitruvius to be the best    proportion

Diastyle

Three diameters

Araeostyle

Four or more diameters, requiring a wooden architrave rather than one of  stone

Araeosystyle

Alternating araeostyle and systyle
