25 Block Circle Generator

Twenty-five blocks is the most requested circle size, and for good reason. It is large enough to look genuinely round, small enough to build in one sitting, and being odd it has a single center block to measure from.

Always exactly half the diameter. An odd diameter has a half-block radius but still uses one single centre block.

Mirror mode shows one quadrant only. Build it, then mirror it left/right and front/back for a perfectly symmetrical shape.

Block counts for a 25 block circle

  • Hollow outline (1 block wall): 68 blocks
  • Filled disc: 489 blocks
  • Widest row: 25 blocks
  • Center: one single center block

Building advice for this size

  • Stand on the center block and count 12 blocks outwards to find each of the four widest points.
  • The blueprint's longest run is 9 blocks wide at the top and bottom of the ring — get those right and the curve reads correctly from the ground.
  • This size suits a round tower base, a colosseum wall, a farm plot or the footprint for a 25 wide dome.
  • If you plan to build a matching dome, keep the diameter at 25 so the dome crown sits on one block.

Other circle sizes

Smaller: 20 block circle. Larger: 30 block circle. Or open the full circle generator for any diameter up to 256.
