What this tool does

Find the right weighted blanket weight — the standard guide of about 10% of body weight — with a safe range and the blanket dimensions for your bed size. The 10% rule is a general comfort guideline for adults, not medical advice. Weighted blankets are not recommended for children under 3 or anyone who cannot remove the blanket themselves; consult a clinician for therapeutic use.

How to use the Weighted Blanket Calculator

  1. Enter or select body weight (pounds).
  2. Enter or select bed size (for blanket dimensions).
  3. Read the calculated result; change any measurement to compare alternatives.

Formula

Recommended weight = 10% of body weight (the widely published occupational-therapy guideline), with a comfort range of 8-12%. Blanket dimensions are the standard mattress dimensions for the selected bed, with no overhang added.

Frequently asked questions

The standard guideline is about 10% of your body weight: a 150 lb person lands on a 15 lb blanket, with 12-18 lb (8-12%) as the usual comfort range. This calculator shows all three numbers.

No — beyond about 12% of body weight most people feel restricted rather than soothed, and the blanket gets hard to move. If you are between stock weights (they step by 5 lb), choose the lighter one.

A queen mattress is 60 x 80 inches. Weighted blankets are usually sized to the mattress top with little or no drape (so the weight stays on the sleeper), unlike a regular duvet that overhangs.

Base the weight on the lighter partner if you share, or use two twin-size blankets — a king blanket weighted for a combined body weight would be far too heavy for either person alone.

Never for under-3s, and for older children the same 10% rule applies with adult supervision and only if the child can lift the blanket off themselves. This tool's minimum input reflects adult/older-child weights only.
