# Best flat irons that also curl and wave Source: https://plateandwand.com/best/best-flat-iron-for-curls Publisher: Plate & Wand. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://plateandwand.com/how-we-pick A flat iron can curl and wave, but only if the outside is shaped for it. Square housings with sharp edges leave dents when you twist them. Irons built for curling have a rounded barrel, a heated outer housing or a curl setting, so hair slides around the body as you turn and pull. That lets one tool cover sleek straight days and wavy days. This guide compares seven irons whose listings say they curl or wave, and records how each one does it: a rounded barrel, a heated outer housing or a dedicated mode. We also list plate width, since 1 inch plates make tighter curls than 1.25 inch ones, plus temperature, the number of heat settings and voltage where stated. ## Picks ### 1.
