Sèvres wasn't fair, as it dismembered Turkey. Saint-Germain-en-Laye wasn't fair, as it dismembered Austria. Trianon wasn't fair, as it dismembered Hungary. Versailles wasn't entirely fair but it didn't dismember the target nation (of course, it debatably caused WWII). Really the only decent one out of the bunch was Neuilly-sur-Seine.
Germany's territorial losses in Versailles aren't too bad, but the crushing war indemnity payments and the War Guilt Clause make it a lot worse than the border adjustments look on paper.
