I think the answer is thin; the crust is between 3 and 30 miles thick; less than 1% of the diameter of the Earth.
That's called the crust. The size of the crust compared to the size of the Earth's mantle can be compared to the size of the radius of an apple as the mantle and the apple's skin as the thickness of the crust. the crust is broken up into several plates that float and move around on the mantle's molten surface.
The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. Deep below the Earth's surface, subduction causes partial melting of both the ocean crust and mantle as they slide past one another.
Crustal shortening is the reduction of the size of the Earth's crust through tectonic activities such as those found at a convergent plate boundary. When an oceanic crust collides with a continental crust, the denser oceanic crust subducts beneath the continental crust. This causes the oceanic crust to be subducted back into the mantle and melt, reducing the size of the crust. When two continental crusts collide and neither subducts, the material is being pushed up towards Earth's surface, resulting in mountains like Mount Everest. This causes the crusts to reduce in size.

they are the same exact size

Because by actual measurement, the "crust" of the earth, in relation to the size of the earth, is just about as thick as the skin of the apple in relation to the rest of the apple.
it is smaller than pluto.
1/6th the size.
Mars has a diameter about 0.53 of the Earth's. Mars has a mass about 0.107 times the Earth's.

The amount of crust present on Earth always stays the same. The amount of crust descending into the mantle is balanced by the amount of crust formed at mid-ocean ridges.
As new oceanic crust is being made in one area older crust is being subducted, (pushed or pulled down), in another area, so Earth stays about the same size.
