> The weighted blanket calculator recommends how heavy a weighted blanket should be – about 10% of body weight – for one person or a couple, rounded to standard blanket weights.

## Inputs

- Blanket for
- Your weight (lb, kg, g, oz)
- Partner's weight (lb, kg, g, oz)

## Results

- Recommended blanket weight
- Nearest standard weight
- Couple check

## Formula

```
Single: blanket ≈ 10% of body weight + 1–2 lb
Couple: blanket ≈ 7.5% of combined weight
Round to the nearest standard weight (5, 7, 10, 12, 15, 20, 25, 30 lb)
```

## Explanation

Weighted blankets use evenly distributed glass beads or pellets to provide gentle pressure, which many people find calming. The widely used guideline is about 10% of body weight. Weighted blankets are not recommended for infants and toddlers, and children and people with medical conditions should check with a doctor first.

### How to use the Weighted Blanket Calculator

- **Blanket for**
- **Your weight**
- **Partner's weight**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Choose single or couple, and enter your weight (and your partner's for a shared blanket).

### Tips

- Measure over thin clothing with a soft tape held snug but not tight, and keep the tape level all the way round.
- Take each measurement twice; if you are between sizes, the larger size is usually the safer choice.
- Size charts vary by brand and country – check the maker's own chart when it is available.
- For sewing projects, pre-wash fabric before cutting and buy 10% extra for shrinkage, pattern matching and mistakes.

### Common mistakes to avoid

- Mixing inches and centimetres between the tape and the size chart.
- Forgetting seam and hem allowances when cutting fabric.
- Measuring an old, stretched garment instead of your body.
