The planets are normally classified in size by their equatorial diameter.
The small planets are the ones smaller than 8000 miles in diameter. The large planets are the large ones larger than 30,000 miles in diameter.
They just are. Theres nothing you can do about it.
Let's see now, the Nine Planets web site says the radius of Mercury is 2440, so the diameter ought to be.... 4880 km.
The diameter of Venus is about 12103.6 kilometers or 7520.8 miles. The very slow (clockwise) spin of the planet means that there is no appreciable equatorial "bulge" as is created on Earth and the other planets. The radius of the planet is relatively uniform at approximately 3760 miles. (see related question)
The planets are normally classified in size by their equatorial diameter.
The planets in our solar system, arranged from largest to smallest diameter, are Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury. Jupiter is the largest, with a diameter of about 86,881 miles (139,822 kilometers), while Mercury is the smallest, measuring approximately 3,032 miles (4,880 kilometers) in diameter.

the combined diameter of the inner planets is 22,690 miles, or 26% the diameter of Jupiter.
the combined diameter of all the outer planets is 363,546 kilometers, or 84% the diameter of the sun.
No planet in the solar system has that diameter. The smallest planet, Mercury has a diameter of 4,879.4Km Have you mixed up diameter with radius? If so, Mars is the closest with a radius of 3,396.2km.

Mercury has a very slow spin or rotation about its axis. This means that it is much closer to a spherical shape rather than a flattened or squashed (oblate) sphere like those planets with a much faster rotational spin. This means that The pole to pole diameter is similar to the equatorial diameter. Mercury's diameter is 4879.4km (3031.9 miles).
