Minecraft doesn’t let players place a block on half of a square, as everything has to snap to the same grid. This means that any circle that the player makes while building can at best look like a circle. It’s also important to note that the larger the circle is, the closer it will be to appearing as a true circle.

The first thing players need to do when building a circle is determine what its diameter will be. This is the distance as measured from one end of the circle all the way across to the farthest point on the other side. In Minecraft, it is far easier to build circles with an odd diameter so that a single block can serve as the center point. Choose the center point and build a plus sign to make the skeleton of the circle. For example, if making a circle that has a diameter of 15 blocks, place the central block and then count outwards seven blocks in all four directions to find the outer bounds of the circle.
This is where things get complicated. In terms of a formula, players could use x2 + y² = r², where r is the radius of the circle. With a pen and paper or a graphing calculator, players could graph out the circle and then figure out where blocks could be placed in game to most closely replicate the look of a circle. Thankfully, others have done this work already, and players can benefit from their dedication. Rather than overcomplicate things, use a site like Pixel Circle Generator to easily get a feel for how the circle should look.
When actually going about building the circle, players should always start from one of the four end points of their plus and work towards the middle of an arc. In this way, they will effectively be creating eight smaller arcs, making it much easier to manage than trying to build a full circle all at once. With enough practice, this will likely become second nature.
Minecraft is available now on Mobile, PC, PS4, Switch, and Xbox One.
