how tall is rentarou in 100 girlfriends

Rentarou’s exact height is not officially stated in either the anime or manga of The 100 Girlfriends Who Really, Really, Really, Really, Really Love You as of mid‑2026.

Quick Scoop

Even detailed character info sources and fan guides only confirm:

• Rentarou is 15 years old.

• His birthday isn’t clearly given, just that he’s a Taurus, with one chapter implying May 1 as a likely date.

• These same sources explicitly note that his height is “unknown.”

So if you’ve been looking for a precise number like “170 cm” or “5'7",” that just doesn’t exist in any official material yet.

What fans usually infer

Because the series shows him standing next to his girlfriends a lot, fans sometimes estimate his height based on:

• Visual size comparisons in anime scenes and promotional art.
• YouTube “height comparison” videos that line up the cast and suggest rough ranges for the girls, often marking who is shorter or taller than Rentarou.

• A fan‑made family height chart that tries to place Rentarou among his relatives and girlfriends.

These are fun fan projects, but none of them are canon numbers; they’re educated guesses built from visuals.

So… how tall is Rentarou?

Right now, the only accurate way to answer your question is:

Rentarou Aijou’s height hasn’t been officially revealed; it’s listed as unknown in current character data and guides.

If the author or official anime materials ever publish a character sheet with a specific height, that would replace the current “unknown” status—but as of 2026, we just don’t have that detail. TL;DR:
Rentarou’s height is never given in official sources; guides and articles explicitly say his height is unknown , so any specific number you see is fan speculation, not canon.
