When designing a laboratory, one of the most crucial steps is choosing the right furniture with proper dimensions. Whether you’re planning a school lab, a research facility, or a cleanroom, selecting lab furniture that suits your workflow, safety standards, and spatial constraints is key to a functional and efficient environment.
In this guide, we’ll walk you through standard lab furniture dimensions and practical tips to help you make informed decisions.
1. Standard Lab Table Dimensions
Lab tables (also called lab benches) come in various sizes depending on their application.
-
Height:
-
Standard height: 36 inches (91.4 cm) – suitable for standing work
-
Optional height: 30 inches (76.2 cm) – for seated workstations
-
-
Depth:
-
Common depth: 24 inches (61 cm) to 30 inches (76.2 cm)
-
For heavy-duty applications: up to 36 inches (91.4 cm)
-
-
Width:
-
Standard widths range from 48 inches (121.9 cm) to 96 inches (243.8 cm), depending on lab size
-
Tip: Always leave a minimum aisle clearance of 48 inches (122 cm) between benches for easy movement and safety compliance.
2. Wall Cabinets and Storage Units
Storage is essential in any lab for organizing chemicals, tools, and equipment.
-
Wall cabinet height: 24 to 36 inches (61–91.4 cm)
-
Cabinet depth: 12 to 15 inches (30.5–38.1 cm)
-
Base cabinet height: Typically 34–36 inches (86.4–91.4 cm) including countertop
Tip: Opt for chemical-resistant materials if storing reagents or flammable substances.
3. Fume Hood Dimensions
Fume hoods protect users from toxic fumes and are often required by safety regulations.
-
Width: 48", 60", 72" (122–183 cm)
-
Depth: 30"–36" (76–91 cm)
-
Height: 54"–60" (137–152 cm) (hood only), but with base: ~84" (213 cm) total
Tip: Ensure adequate ventilation and clearance behind and above the hood for ducting.
4. Sink Dimensions
Laboratory sinks must be both functional and durable.
-
Sink basin dimensions:
-
Width: 18"–24" (45.7–61 cm)
-
Depth: 8"–12" (20.3–30.5 cm)
-
Length: 18"–30" (45.7–76.2 cm)
-
-
Height from floor: Usually 36" (91.4 cm) including countertop
Tip: Choose epoxy resin or stainless steel for durability and chemical resistance.
5. Lab Stool and Chair Heights
For seated workstations:
-
Seat height: 18"–24" (45.7–61 cm) for standard tables
-
For 36" high benches: stool height should be 24"–30" (61–76 cm)
Tip: Adjustable height and anti-fatigue features improve long-term comfort and productivity.
6. Custom Lab Layout Considerations
When designing a lab space, also consider:
-
Aisle width: Minimum 48" (122 cm)
-
Clearances: Leave at least 36" (91 cm) behind seated users
-
Work triangle efficiency: Optimize the placement of sinks, benches, and storage
