# Best long barrel curling irons for long hair Source: https://plateandwand.com/best/best-curling-iron-for-long-hair Publisher: Plate & Wand. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://plateandwand.com/how-we-pick Long hair runs out of barrel. On a standard iron, a section from a long layer wraps over itself and the curl comes out uneven, or you have to split it into more sections. Two specs fix that. Barrel length decides how much of a long section fits in one wrap, and barrel size decides whether the result is a defined curl or a loose wave. For long hair, 1.25 to 1.5 inch barrels are the usual pick for soft, full curls. Heat control matters next: Bio Ionic and T3 let you choose a setting, while ghd holds 365°F. This guide compares six curlers over $150 that the listings describe as long, extra-long or suited to longer hair. For each we list barrel size, barrel length, top temperature, heat settings and clamp from the Amazon listing, and mark anything missing as Not stated. ## Picks ### 1.
