The Ten Inch Rule
Hammerton co-founder Levi Wilson inspired Hammerton’s guiding principle, the ’Ten Inch Rule,’ which requires each fixture to withstand an uncompromisingly scrupulous eye from less than a foot away.
It’s a standard that puts the smallest details under scrutiny. From a perfectly finished weld to the way glass meets metal, every element is considered for how it looks, feels, and functions up close. What may go unnoticed across a room becomes important at ten inches.
The rule also leaves room for something uniquely Hammerton: the character of the handmade. Artisan-cast and hand-blown glass can have subtle variations, while hand-worked metal can reveal the marks and texture of the process. These details are carefully refined to make each fixture feel intentional from every angle.
Before a fixture leaves Hammerton, it passes through multiple stages of inspection to ensure it meets our standards for construction, finish, and overall quality. Our team examines the details that are easy to overlook, from surface consistency and connections to the precision of individual components.
For designers, that means specifying Hammerton with confidence that the fixture will deliver more than impact from a distance. It will hold up to closer inspection in the spaces where people gather, live, and work. The Ten Inch Rule is our commitment to lighting that rewards a closer look, because exceptional design is often found in the details.
