How big is the average kidney?

My recent sonography report mentioned something about my kidneys, and I just want to understand what's considered a normal size for them. Doc said everything is fine, but I'm curious to know the average.

Honestly, it is actually just the size of our fist only. Normal people think it is very big, ho na? But my doctor told me it's only about 10 to 12 centimeters long. Very small but does such heavy work for our body!

I totally get why you are asking this, I also spent hours googling kidney sizes when my back started aching last year. It is usually just about 4 or 5 inches long, like a small mobile phone. Please don't stress yourself out reading scary medical stuff online, just consult a doc if you feel uneasy.

It is actually pretty small, yaar! Like almost the size of a computer mouse or a small fist. I was shocked when I saw the ultrasound report of my cousin, it's barely 11-12 cm.

Beta, the average adult kidney is roughly 10 to 12 cm in length and about 5 cm wide. Think of it like a normal-sized mango. Unless your doctor has pointed out any swelling in your sonography, you don't need to worry about the size at all.

It is about 10-12 cm long. Because I have diabetes, I have to get my kidney function and microalbumin tests done every year to make sure they aren't getting damaged or swollen. Keep your blood sugar in check to keep your kidneys healthy.

If you want a food comparison, it is basically the size of a large rajma bean, just scaled up to the size of a small pear! It's amazing how that tiny thing handles all the water and salty snacks we hog daily.
