A desk that’s too small means elbows off the edge and papers on the floor; too big and it swallows the room. The right size depends entirely on how you work — laptop, monitors, paperwork. Our free desk size calculator sizes the desk to your actual setup. Run it once and the desk size calculator gives you a work-ready answer, grounded in classic desk ergonomics.

What the Desk Size Calculator Tells You (Specifications)

• Inputs: your setup (laptop, single monitor, dual monitors, creative/drafting) and how much paperwork space you need.
• Ideal width — from 44″ for laptop-only up to 72″+ for creative work, plus paperwork allowance.
• Ideal depth — 24–30″, keeping screens at a healthy 20–28″ viewing distance.
• Height and room guidance — 28–30″ standard height, 36″ clearance behind the chair.

How to Use It — Step by Step

1. Choose your setup — be honest about monitors, not aspirational.
2. Add paperwork space — minimal, some, or lots.
3. Hit calculate and note the width x depth.
4. Check your room — the desk plus 36″ behind the chair must fit.
5. Light it right with our lighting calculator — task lighting matters as much as desk size.

Designer Tips for Desk Sizing

• Depth matters more than people think. 30″ deep keeps monitors at eye-safe distance and leaves a writing strip in front.
• Dual monitors need 60″+. Anything less and you’re craning your neck all day.
• Cable-manage first. A tidy 48″ desk feels bigger than a messy 72″ one.
• Sit-stand is worth it if you work 6+ hours — your back will vote yes.
