Both are New Balance models, but lasts differ. 574 is labeled True to Size (True to size; use width letters (D/2E) instead of guessing length). 327 is Runs Narrow (True to size in length; half up if wide or between sizes).
New Balance 574 is generally true to size with a relatively accommodating toe box on the SL-2 last. Between sizes, many lean half up. Prefer official width options over length tricks if you already know you need wide.
New Balance 327 is usually true to size in length but slimmer through midfoot and toe than 574/990s. Narrow-to-average feet TTS; wide feet often go half up because wide widths are rarely offered. Coming from Nike, some also prefer half up.
Use the table below as a starting point from fit offsets — then confirm with try-on or returns. Width can matter more than length between these two.
