How the Calculator Works

The calculator uses practical ergonomics to estimate a chair that supports your posture while distributing pressure comfortably. Behind the scenes, it applies simple rules of thumb used by furniture designers and therapists:

  • Seat widthSeated hip width + ~4 in of wiggle room.
  • Seat depthButtock-to-knee length − ~2 in so your knees aren’t compressed.
  • Seat heightFloor-to-knee height so feet rest flat and thighs are supported.
  • Back heightSeated shoulder height + ~4–6 in for head/neck support.
  • Overall width (estimate)Seat width + ~8 in for two armrests.
  • Capacity class is matched to your weight with headroom for daily use.

Tip: If you leave any field blank, the calculator estimates it from your height to keep things moving.

L22–2420–2228–34Up to ~350 lb
XL24–2621–2330–36400 lb+

What to Measure (and How)

  1. Height — Your overall height standing. Used to estimate any missing fields.
  2. Weight — For capacity class; choose more headroom if you prefer a firmer feel (see heavy-duty recliner 400 lb options).
  3. Hip width (seated) — Sit on a firm chair. Measure the widest point across the hips.
  4. Buttock-to-knee (BKL) — From your seat back to the crease behind the knee.
  5. Floor-to-knee height — From the floor to the top of your knee while seated.
  6. Shoulder height (seated) — Seat surface to top of shoulder for proper headrest alignment (or add a headrest pillow).
  7. Room width & wall clearance — Maximum overall width you can fit and the space behind the chair. Tight spaces point you toward a wall-hugger recliner.

Interpreting Your Result

  • Recommended size (S/M/L/XL): The closest match across seat width, depth, and back height.
  • Capacity tag: Choose equal or higher rating than your weight for durability.
  • Type: With limited clearance, look for a Wall-Hugger or glider/rocker recliner, depending on space.
  • Overall width (est.): If it’s near your room limit, consider a space-saving narrow-arm recliner.

Step-by-Step: Using the Calculator

  1. Select in/lb or cm/kg.
  2. Enter the measurements you know; leave blanks to auto-estimate from your height.
  3. Optional: Add Room width and Wall clearance for more precise recommendations.
  4. Review the Recommended Specs table and the quick fit notes.
  5. Start browsing models that match your result:
    power lift recliner,
    wall-hugger,
    glider/rocker

Shopping Filters & What to Look For

  • Seat measurements: Compare the product’s seat width/depth/height to the calculator’s values.
  • Back/Head support: Tall users often prefer 30–36 in back height (or add a headrest pillow).
  • Capacity: For stronger frames/mechanisms, explore heavy-duty (400 lb) recliners.
  • Clearance: If close to a wall, verify fully-reclined clearance or choose a wall-hugger.
  • Arms: Narrow or track arms can shrink footprint without sacrificing seat size—see narrow-arm recliners.
  • Upholstery: Leather/PU wipes clean easily; performance fabrics resist spills and pilling. Protect finishes with a recliner protector.

Example Scenarios

“Tight space against a wall”

Enter your Wall clearance in the calculator. If you’re at ~6 in or less, it will flag a wall-hugger recliner. Pair that with your size class and, if needed, a narrow-arm design.

“Big & Tall with wide shoulders”

Focus on back height and capacity. The calculator might suggest L or XL with a higher rating. Browse heavy-duty recliners (400 lb) and add a headrest pillow if you’re between sizes.

“Narrow doorway or hallway”

Use the Overall width (est.) and measure your path to the room. If it’s close, target a narrow-arm recliner or space-saving frame and check boxed dimensions.


Disclaimer: The calculator provides a practical starting point for fit and comfort. Always confirm the manufacturer’s published measurements and weight rating before purchase. When possible, try seating in person—your posture, mobility, and cushion preferences matter.
