How to measure mortar distance on Deston
Step by step
- 1Open the Deston top-down map above.
- 2Scroll-zoom into the area you're firing on. The calculator stays calibrated at any zoom up to 6×.
- 3Click your firing position — the first click drops marker A.
- 4Click your target — the second click drops marker B and reveals the in-game distance in meters.
- 5Match that number to the closest mark on your mortar's elevation indicator and fire.
Pro tips
- •Deston is square: every horizontal line of grid squares is exactly 1 km wide if you're on an 8×8 km map, or proportional for other map sizes. Use the grid as a sanity check.
- •The mortar arcs high, so trees, ridgelines and tall buildings between you and the target rarely block the shot — but they can swallow it on the way down. Pick targets in open clearings whenever possible.
- •Hold Shift and drag (or middle-mouse drag) to pan once you've zoomed in. Click 'Clear' or just click anywhere a third time to start a fresh measurement.
Frequently asked questions
How does the PUBG mortar ruler work?+
Click any two points on the Deston map. The first click sets your firing position, the second click sets your target. The ruler measures the straight-line pixel distance between the two points and converts it to in-game meters using the official 8×8 km grid for Deston. The result tells you the distance you need to dial into the mortar's elevation marks.
How accurate is the mortar distance calculator?+
Calibration uses KRAFTON's official map dimensions: Deston is 8 km on each side. Pixel-to-meter conversion is exact at any zoom level because the canvas re-derives the ratio from the rendered image size on every measurement. The only source of error is your own click precision, which is why the tool ships with zoom up to 600% so you can place each marker on the exact building or grid square.
What is the maximum range of a PUBG mortar?+
The PUBG mortar fires from roughly 50 meters out to 700 meters with elevation marks in 50-meter increments. Use this calculator to read the meter value, then match the closest mark on the mortar's elevation indicator. Wind and elevation differences between firing position and target are not accounted for in the marks themselves, so adjust by feel for big height deltas.
Can I use the mortar ruler on every PUBG map?+
Yes. The calculator ships every official KRAFTON map: Erangel, Miramar, Sanhok, Karakin, Paramo, Taego, Deston, Vikendi, Rondo, Haven and Camp Jackal. Each map is calibrated to its real in-game grid size, so the same two clicks always produce the right number of meters regardless of which map you pick.
Why are there two map variants (clean and labeled)?+
Clean maps (no text labels) make it easier to spot the exact terrain feature you're firing at. Labeled maps show town and POI names, which is handy when callouts come over comms. Toggle between them with the 'Show labels' switch — your preference is saved in your browser.
