How to Choose the Right LED Panel Light Size for Your Office Ceiling Grid

How to Choose the Right LED Panel Light Size for Your Office Ceiling Grid

One of the most common mistakes B2B buyers make when ordering LED panel lights for the first time is overlooking the ceiling grid size — ordering the wrong panel dimension means a fixture that simply does not fit into the existing suspended ceiling system, resulting in costly reorders and project delays.

Standard Panel Sizes and Ceiling Grids

• 600x600mm — fits standard square suspended ceiling grids common in offices, schools, and commercial buildings across Europe, the Middle East, and Asia.

• 300x1200mm and 300x600mm — fit rectangular grid systems common in corridors, narrow offices, and retrofit projects.

• 605x605mm — a slightly larger variant used in certain South American markets such as Argentina, where local ceiling grid standards differ slightly from the 600x600mm international standard.

How to Confirm the Right Size Before Ordering

Before placing a bulk order, measure the actual ceiling grid opening on site, not just the stated "standard" size — older buildings and different regional grid systems can vary by several millimeters, which matters when the panel needs to drop cleanly into the grid without visible gaps.
