Both are New Balance models, but lasts differ. 327 is labeled Runs Narrow (True to size in length; half up if wide or between sizes). 574 is True to Size (True to size; use width letters (D/2E) instead of guessing length).
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.
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.
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.
