Formula Used

The core formula multiplies body mass by a chosen percentage:

target_weight = body_weight × (percentage ÷ 100)

Typical guidance:

Adults: 8%–12% of body mass. Medium sensitivity often prefers ~10%. Low sensitivity may enjoy 10%–12%, high sensitivity 8%–10%.
Teens: 7%–10%. Start near 8%–9% and adjust by comfort.
Children (3–11): 5%–10%. Do not exceed 10% and ensure the child can independently remove the blanket.
Couples: Use the average of both bodies and aim for 7%–10% to balance preferences. Some prefer separate blankets.

This tool is for comfort guidance only and is not medical advice. People with respiratory, circulatory, or mobility concerns should consult a clinician.

FAQs

1) Is a heavier blanket always better?

Not necessarily. Heavier can feel restrictive. Start in the recommended range and adjust based on comfort and mobility.

2) What if my chosen percentage is outside the safe range?

The calculator will warn you. Staying within the recommended range is advised, especially for kids and sensitive sleepers.

3) How should I pick size?

Choose a size that drapes the sleeper without overhang to avoid sliding off. Match to bed size but many prefer slightly smaller than the mattress footprint.

4) Which fill should I choose?

Glass beads feel thinner and quieter. Plastic pellets add loft and warmth. Micro steel is very dense. Personal preference and climate matter.

5) Are weighted blankets safe for children?

Only for children 3 years and older who can easily remove the blanket. Keep within 5%–10% and supervise initial use.

6) What about hot sleepers?

Pick breathable covers like cotton or bamboo and consider lower percentages. Avoid excessive overhang that traps heat.

7) Do medical conditions change the guidance?

Yes. If you have respiratory, circulatory, joint, or mobility issues, consult your clinician before use.
