Here is a poster by Gravitation Innovation with Saturn V and SpaceX Starship at launch pad. Jan 13, 2019 - Comparison of the full stack Starship + Super Heavy, the most powerful rocket ever built - Saturn V - and today's workhorse of SpaceX - Falcon 9; made by Finnish 3D artist Kimi Talvitie.

The internal fuel tanks probably are about the size of the New Glenn. Artist's illustration of NASA's Space Launch System (SLS) rocket on the pad. But where the Falcon Heavy comes out ahead is in economy. A prototype to test VTOL operations with the new engines is being built outdoors. The Saturn V deserves credit, where credit is due. You might ask how can a more powerful rocket only get half the payload to the moon as the Saturn V? SpaceX's Mars rocket may be millions of pounds heavier and dozens of feet taller than the Apollo-era Saturn V, which sent astronauts to the moon.

The BFR is a planned system of two stages, both reusable. Next up, we have the Saturn V that could send 48.6 tonnes to the Moon.
Then SLS Block 1, which can take 27 tonnes to TLI. But right now SpaceX is building even more powerful rocket for Mars - Starship. Total booster thrust would have been approximately 130 MN (29,000,000 lbf), several times the 36 MN (8,000,000 lbf) thrust of the Saturn V Moon mission launch vehicle. Of course, the hopper won't carry that much fuel for hop tests. I love how everyone is so quick to rib on the Saturn V, and say how cool starship is. The estimated cost of a Saturn V launch in today's dollars is a whopping US$1.16 billion. They aren't wrong about starship, its gonna be cool. Saturn V vs SLS. Yes, NASA's New Megarocket Will Be More Powerful Than the Saturn V. By Mike Wall 16 August 2016. The upgrade 1B version should put 43 tonnes into TLI. Just remember that the Saturn V actually existed/flew (in th 1960s) successfully, something starship has yet to do. Shares. The upper stage will have a lot of windows.

What I'm getting out of this is that we're looking at a hopper that is about the same size as the second stage of the Saturn V. Which wasn't exactly tiny. Today 50 years ago the most powerful rocket ever built - Saturn V - launched first astronauts to set foot on the Moon.
The design engine configuration included 21 engines in an outer ring and 14 in an inner ring, with these 35 engines fixed in place.
