It looks like you’re asking about the height of Alexandra Leclerc (almost certainly referring to Alexandra Saint Mleux, Charles Leclerc’s partner, whose name is often shortened or mixed up as “Alexandra Leclerc” online). Based on publicly available info, her height is not officially confirmed, but most reliable fan and media estimates place her in the 5'6"–5'7" range (about 168–170 cm).

Because there is no verified official statement from Alexandra herself or from a formal biography, everything online is essentially an estimate or comes from fan discussions and celebrity info sites, which sometimes disagree by a couple of centimeters. Some fan forum posts mention that she has said 168 cm (about 5'6") in a TikTok, while several entertainment/celebrity sites list her at around 5'7" (170 cm), which explains why you’ll see slightly different numbers depending on where you look.

So the most honest, non-clickbait answer is: she is widely reported to be around 5'6"–5'7" (≈168–170 cm) , but there is no fully authoritative, official height listing publicly available.
