GAME & ENTERTAINMENT – BOARD GAME & TABLETOP CALCULATOR
Line Of Sight Range
A precise tool.
What is the Line Of Sight Range & How does it work?
Understanding lineβofβsight is essential for tabletop miniatures, as it determines whether a model can see and target another across the battlefield.
The sight line can be modelled as a rightβangled triangle where the vertical leg represents the height difference between the observer and the target, and the horizontal leg represents the measured distance on the table.
\theta = \arctan\left(\frac{h_{target} – h_{observer}}{d}\right)
ΞΈ = angle of sight
By comparing the angle to any intervening obstacles, players can quickly decide if a line is blocked, making combat more realistic and faster to resolve.

Frequently Asked Questions
How do I calculate the angle of sight in a tabletop game?
Use the formula ΞΈ = arctan((h_target – h_observer) / d), where h_target is the target’s height, h_observer is the observer’s height, and d is the horizontal distance.
What does line-of-sight determine in tabletop miniatures?
Line-of-sight determines whether a model can see and target another across the battlefield.
How do I measure height difference in a tabletop game?
Measure the vertical distance between the base of the observer’s model and the base of the target’s model.
Can you explain how the right-angled triangle is used in this calculation?
The right-angled triangle represents the line-of-sight, with the vertical leg as height difference and the horizontal leg as distance on the table.
What if there are obstacles between the observer and target?
Compare the calculated angle to any intervening obstacles’ angles to determine if they block the line of sight.
Is this calculator useful for all types of tabletop games?
Yes, it’s particularly useful for wargames and miniature battles where visibility is a key factor.
How do I interpret the result once I have calculated the angle?
If the angle is less than or equal to the observer’s field of view, they can target the object; otherwise, it’s out of sight.
