No. Letter size refers to the sheet dimensions, while Avery style describes the tab arrangement and printed format. A filing system built around legal size dividers, bottom tabs, another hole pattern, or a different tab position may not align correctly. Systems using formal legal indexes can also follow specific title, size, and tab conventions. Confirm sheet dimensions, side tab placement, printed number style, tab extension, and binding method before ordering replacements. These dividers are unpunched, which allows hole placement to suit the intended binder or binding system, but the punch still needs adequate margin and alignment. Place one existing divider over a sample sheet to verify the outer dimensions and tab position before purchasing a large quantity.
