What Size Grounding Sheet Do I Need?
3 min readTL;DR: Key Takeaways
- Measure, do not trust the name: a “King” in the UK, Lithuania and the United States are three different mattresses, so the measurement is the reliable thing.
- Fitted sizes: 100 × 200, 140 × 200, 160 × 200, 180 × 200 and 200 × 200 cm.
- Between two sizes, take the larger: a slightly generous fitted sheet tucks; a slightly small one does not reach.
- Half-sheet alternative: at 146 × 200 cm (57.5 × 78.7 in) a half sheet covers the torso area and suits a shared bed where only one person wants it.
Measure your mattress width and length in centimetres and match it to the chart below. Bed names differ between countries — a "King" in the UK, Lithuania and the United States are three different mattresses — so the measurement is the reliable thing and the name is not.
Measure the mattress itself, not the frame, and note its depth too: our fitted sheets are cut with a generous pocket, but a very deep mattress with a topper is worth checking.
What sizes do the fitted grounding sheets come in?
The Natural Fitted Grounding Bed Sheets are made in these sizes:
- 100 × 200 cm (39.4 × 78.7 in) — Long Single
- 140 × 200 cm (55.1 × 78.7 in) — Double
- 160 × 200 cm (63.0 × 78.7 in) — Euro King
- 180 × 200 cm (70.9 × 78.7 in) — Super King
- 200 × 200 cm (78.7 × 78.7 in) — Emperor
Every fitted size is cut with a +40 cm (15.7 in) pocket, which is what lets it sit over a deep mattress, or over a mattress with a topper underneath the grounding sheet.
How do EU sizes map to UK and US mattresses?
| Mattress | Size | Closest sheet |
|---|---|---|
| UK Single | 90 × 190 cm (35.4 × 74.8 in) | 100 × 200 |
| UK Double | 135 × 190 cm (53.1 × 74.8 in) | 140 × 200 |
| UK King | 150 × 200 cm (59.1 × 78.7 in) | 160 × 200 |
| UK Super King | 180 × 200 cm (70.9 × 78.7 in) | 180 × 200 |
| US Queen | 152 × 203 cm (59.8 × 79.9 in) | 160 × 200 |
| US King | 193 × 203 cm (76.0 × 79.9 in) | 200 × 200 |
Where a mattress falls between two sizes, take the larger sheet. A slightly generous fitted sheet tucks; a slightly small one does not reach.
What if I do not want to cover the whole bed?
A half sheet covers the torso area and leaves the rest of the bed as it is. The Grounding Half Sheet and the High-Silver Grounding Half Sheet at 146 × 200 cm (57.5 × 78.7 in) both work this way, and both suit a shared bed where only one person wants the sheet.
Which plug adapter do I need?
The sheet is the same wherever you are; the adapter is what changes. Match your country's outlet type:
- Type C/F (Schuko) — most of continental Europe: Type F adapter
- Type G — UK and Ireland: Type G adapter
- Type A/B — United States and Canada: Type A/B adapter
- Type I — Australia and New Zealand: Type I adapter
- Type K — Denmark: Type K adapter
- Type D — India: Type D adapter
- Type M — South Africa: Type M adapter
- Type H — Israel: Type H adapter
If you travel, the Universal Grounding Adapter covers several types in one kit.

Frequently Asked Questions
Should I size up for a deep mattress?
If your mattress is unusually deep, or you use a thick topper under the sheet, the larger size gives you the pocket depth to tuck properly.
Does the sheet size change how well it works?
No. The connection depends on skin contact with the conductive fabric, not on how much of the bed is covered. A half sheet connects the same way a full fitted sheet does.
Can I use a EU-size sheet on a US bed?
Yes, within reason — see the chart above. A US Queen at 152 × 203 cm (59.8 × 79.9 in) takes the 160 × 200 sheet.
Do I need one adapter per sheet?
One per cord. The dual-port adapters take two cords, which covers a sheet plus a mat from a single outlet.
