A portable modular folding table can include a substantially flat tabletop having three or more tabletop sections, hinges coupled to the tabletop sections, and collapsible legs that are modular and separate from the tabletop. The tabletop can have a width and a length that is at least twice as large as the width, and the tabletop sections are coupled to and foldable onto each other to reduce the length of the tabletop by less than half when the tabletop is reduced from a fully extended configuration to a fully compacted configuration. Each of the collapsible legs can be adjustable to multiple different heights and can have multiple tabletop support points. The tabletop can rest atop the tabletop support points when the tabletop is in a fully extended configuration and the tabletop can be separated from and stored alongside the collapsible legs when the tabletop is in a fully compacted configuration.
