Deep Strike Ruler Template 6""

A 6-inch Deep Strike Ruler for Rapid Deployment is a straight measuring piece with a curved exterior, made of acrylic, that measures exactly six inches—the safe distance certain miniatures must maintain when entering the table from reserve in Warhammer 40,000.®when they have abilities that reduce the standard margin. This 100% compatible tool is cut from 3mm fluorescent acrylic and is just the right thickness to slide between tightly packed scenery without dislodging it. Being a rigid piece—not a tape measure—it can be laid flat against a miniature's base and rotated to draw a perfect six-inch exclusion circle in any direction.

For those special Rapid Deployment rules in 10th Edition, a unit can deploy "at any point on the battlefield that is more than 6 inches horizontally from all enemy miniatures" during your Reinforcements Pass. The distance is measured from base to base (or hull to base in vehicles) on a horizontal plane—height is ignored—so a reliable six-inch caliper is essential.

During the game, the 6" rule speeds up deployment: you touch one end to the nearest enemy base, pivot the piece to draw an invisible circle, and instantly locate the nearest legal drop point. Many players use it before the game starts, circling key objectives to visualize forbidden areas that the opponent won't be able to use on turn 2. The fixed length prevents unintentional compression or stretching of a tape measure, giving both sides identical and verifiable measurements.

Because arguments about "eyeballing" six inches can slow down tournaments, referees often recommend or even facilitate these rules. A single fluorescent marker is more visible than faint meter markings, so opponents can check distances at a glance instead of measuring multiple times. This consistency speeds up rounds and prevents a unit from ending up too close. Any unit with Rapid Deployment, Teleportation, Null Deployment, or other rules that specify 6" benefits from the tool—for example, Blood Angels with Descent of Angels, T'au with Air Caste Positioning, or Drukhari Raiders with Raid from the Skies. Additionally, the six-inch border serves as a quick reference for Advance+Move combinations, reduced Heroic Intervention bubbles, and custom Objective Control radii. In short, the 6" Ruler is a small investment that pays for itself every time reinforcements arrive, keeping your deployments legal and conflict-free.

GSW's version looks like it came straight out of a neon-lit sci-fi cockpit: laser-cut from clear fluorescent acrylic, it catches the ambient light and glows at the edges, so the etched markings stay crisp even in dimly lit rooms. The 3mm thickness keeps it perfectly rigid, while the polished bevel allows it to slide between grouped miniatures without scratching the paint.
