RulerMod
by Beo2011_
With RulerMod, a player marks two positions in the world and sees the selected area as a holographic 3D box.
What it does
Pressing R turns the ruler on. Clicking a block with the left button assigns the first position, while a right-click assigns the second, and the resulting selection appears at once as a holographic wireframe box in the world. Single positions show up as soon as the first one is placed, so the box can be checked before the second point exists. Pressing R again deactivates the ruler and clears the selection. The keybind can be changed under Controls, in the Ruler category.
Each selection is accompanied by its measurements, covering dimensions, distance, and area or volume, which are presented in a compact panel anchored to the top-left of the screen. Edges are color-coded by axis, with X in red, Y in green and Z in blue, and a subtle inner grid helps with spatial orientation. The first position is highlighted in green and the second in red through a transparent block highlight.
RulerMod is built on Fabric and needs Fabric API. It is a client-side only mod: no server install is needed, and the mod works on single-player and on servers without being installed there. It is released under the MIT License, but it is not open source. Files are published for Fabric for three game versions, 1.21.11, 26.2 and 26.3, with 1.0.2 for 26.3 as the latest file.
Key features

Left-click a block to set the first position and right-click to set the second, with the selection drawn as it is made.

The selected area is drawn as a clean wireframe box with chunky, vanilla-style edges and a transparent block highlight.
Live measurements panel
In the upper-left corner, a compact panel lists the size, distance, and area or volume of whatever region is currently selected.
Color-coded axes
Edges use X red, Y green and Z blue, with a subtle inner grid for spatial orientation.
