Signs in Valheim: Fifty Bytes, and Most of Them Go on Styling
A Valheim Sign costs one coal and two wood and holds "written notes (max 50 bytes in UTF-8)". That phrasing is doing something specific, and almost nobody reads it carefully: the limit is bytes, not characters. For an English label those are the same thing. For a Russian, Polish or accented one, you get half as much text — and if you use styling tags, less again.
On sourcing. Iron Gate do not publish system documentation. The figures below come from the community wikis and can change with any patch.
The Sign Itself
| Recipe | Coal ×1, Wood ×2 |
| Durability | 100 |
| Size | 1 × 0.5 |
| Type | Furniture |
| Rain damage | No |
| Character limit | 50 bytes (UTF-8) |
One coal is the only real cost, and as our trophies guide notes, coal is cheap — a Charcoal Kiln produces one from a single unit of wood every 16 seconds. Signs are effectively free.
No rain damage means outdoor signs are permanent, which matters for anything marking a route, a portal or a dock rather than a chest.
The 1 × 0.5 footprint is small enough to fit above a chest, which is what most of them are for.
And they are Furniture, so they place with the Hammer inside a Workbench radius like anything else.
Fifty Bytes Is Not Fifty Letters
UTF-8 encodes different characters in different numbers of bytes, and Valheim's limit is measured in bytes. So the practical character limit depends entirely on what alphabet you write in:
| Text | Bytes per character | Characters you get |
|---|---|---|
| Plain ASCII (a–z, 0–9) | 1 | 50 |
| Accented Latin (é, ö, å) | 2 | 25 |
| Cyrillic (а–я) | 2 | 25 |
| Emoji | 4 | 12 |
An English sign gets fifty characters. A Russian one gets twenty-five. That is not a Valheim quirk so much as a consequence of the encoding, but the effect on a non-English server is real and unexplained in game: your labels have to be half as long.
Mixed text costs proportionally. "Iron ×20" is cheap; "Железо ×20" costs more than twice as much per letter.
Emoji are the expensive case at four bytes each — a dozen of them and the sign is full. A single emoji as a chest icon is a fine use; a row of them is not.
If a sign silently refuses your text, this is why. The game does not explain that the limit is bytes, so a label that fits in English and not in your own language looks like a bug.
Styling Eats the Budget
Signs support styling tags — and every tag spends bytes from the same fifty.
That is the trade the wiki flags directly, noting that adding the full fifty characters "will make the sign illegible unless most extra characters are for Styling." In other words: you are choosing between a long label and a formatted one. You cannot have both.
Which produces the practical rule: one word per sign. A storage room labelled IRON, WOOD, FOOD, ORE is legible from across the hall and costs four bytes a sign. A sign trying to say "Iron and iron scrap, top three chests only" is neither legible nor within budget.
Use signs for labels, not instructions. Anything that needs a sentence belongs in a group chat or a shared note, not on a 1 × 0.5 board that holds fifty bytes.
And label by category rather than by item. Since portal tags have a similar ten-character discipline, a base that uses short consistent names for both is far easier for a group to navigate — MINE, SWAMP, HOME on portals and ORE, WOOD, FOOD on chests.
The one place a long sign earns its bytes is a warning. A sign reading NO TELEPORT above the ore chest saves more confusion than any amount of styling.
Practical tips
- Coal ×1, Wood ×2 — effectively free, and no rain damage.
- The limit is 50 bytes in UTF-8, not 50 characters.
- ASCII gets 50 characters; Cyrillic and accented Latin get 25; emoji get 12.
- Styling tags spend from the same 50 bytes.
- A styled sign is a very short sign. Choose one or the other.
- One word per sign is usually the right answer.
- Use signs for labels, not instructions.
- Match your sign vocabulary to your portal tags for a navigable base.
Running your own Valheim server
A labelled base is a shared base — the whole point of signage is that somebody other than you can find the iron. A gamever Valheim server keeps that world persistent for up to 10 players, with one-click backups so a storage hall organised over weeks stays organised.
Conclusion
A Valheim Sign costs Coal ×1 and Wood ×2, carries 100 durability, takes no rain damage and holds "written notes (max 50 bytes in UTF-8)". That limit is bytes, not characters, which means plain English gets 50 characters, Cyrillic and accented Latin get 25, and emoji get 12 — an unexplained halving for anyone not writing in ASCII. Styling tags spend from the same fifty-byte budget, so a formatted sign is necessarily a short one, and the wiki's own warning is that filling the limit makes a sign illegible anyway. The habit that falls out of all this is simple: one word per sign, used as a label rather than an instruction, with a vocabulary that matches your portal tags so the whole base reads consistently. And keep the long ones for warnings — NO TELEPORT above the ore chest earns its bytes.
