Unless you have a real reason to think you are an outlier you probably aren’t.
There are a hundred fit systems and ten thousand internet opinions about them but there’s only seven bike sizes. 2xs-2xl. That’s only on the most popular models and the smaller ones might be pink with a different model name. A few very popular models might have a “M-L” size. Maybe few as three (M L XL) for more boutique brands. Hard to sell a manly man a “small” anything.
Some brands are half a size off. Notably Salsa, for me. Their M is halfway to a Large. A Cannondale medium fits me spot on at 5-8 but a Salsa I need a stem swap. Their recommended height range reflects this just fine.
