Understanding Herman Miller Chair Sizing

Herman Miller chairs are crafted with precision engineering to support a range of body types. Here are key factors that influence chair size selection and how Herman Miller categorizes their sizing.

Height

Your chair should support your posture from the base of your spine to your neck, and Herman Miller sizes allow you to find an ideal match to avoid slouching or overextending.

Weight

Each chair model has weight capacities, and larger sizes may offer increased durability. Proper weight accommodation keeps the chair’s ergonomic features functioning optimally.

Posture Preferences

Whether you sit upright, recline or move frequently, your ideal chair size should support your posture comfortably. Be sure to select the adaptable features that suit your seating style.

 

Herman Miller’s Sizing System

Herman Miller chairs are often categorized by size markers like A1, A2, A3, B1, B2, B3, and C.

These indicate variations in seat width, depth, and overall dimensions, giving you options that fit both your body and seating preferences.

The Herman Miller Aeron chair comes in three sizes: A, B, and C, with A being the smallest and C being the largest:

• Size A: For people who are 4'8"–5'4" tall and weigh up to 136 kg
• Size B: For people who are 5'2"–6' tall and weigh up to 159 kg
• Size C: For people who are 5'10"–6'7" tall and weigh up to 159 kg 

Here are some other things to consider when choosing a size:

• Seat depth: Make sure there's a couple of fingers' worth of space between the back of your knee and the edge of the seat. 
• Arm width: The width between the arms is about 17" for size A, 18.5" for size B, and 20.5" for size C.  
• Arm height: The arm height is 7.8" for size A, and 8.5" for sizes B and C

 

Choosing the Right Herman Miller Chair Size

Finding the perfect Herman Miller chair size is essential for comfort and support. With this step by step guide, you'll learn how to choose a chair that fits your body and suits your posture preferences.

 

1. Measure Your Height and Weight

Knowing these measurements helps you select a chair with the correct weight capacity and optimal height.

2. Consider Your Posture Preferences

If you prefer to sit forward or recline, think about how you typically use your chair. Herman Miller chairs often come with adjustments that help you tailor your seating to your preferred posture.

3. Refer to the specific model on the Herman Miller website 

Note that only the Aeron chair has a detailed sizing chart (see below), which maps out height and weight ranges to recommend the ideal size. For other models, sizing recommendations may vary or rely on general guidelines.

4. Test the Chair in person (if possible)

Visit an Authorized Herman Miller Dealer showroom in your area to try different sizes in person. Be sure to call ahead to ensure a variety of chairs and a salesperson to answer your questions are available. Experiencing the chair’s comfort firsthand can help you make a confident choice.

Tips for Optimal Comfort and Ergonomics

No matter which Herman Miller chair you choose, keep these ergonomic tips in mind to get the most out of your seating experience.

Adjust Your Chair Properly. Take time to fine-tune seat height, armrests, and back angle to fit your body. Proper adjustments help you maintain a healthy posture.

Practice Good Posture. Keep your feet flat on the ground and align your spine naturally. Avoid slouching or leaning too far back. All the chairs we talk about here will help you do this automatically.

Take Regular Breaks. Even the most ergonomic chair can't replace the benefits of movement. Stand up, stretch, and take a short walk periodically to keep your body flexible and to avoid feeling stiff.
