How To Make Planks in OSRS

Jan 9

In Old School RuneScape, planks are made by converting specific logs into planks for a fixed coin cost, and every Construction method depends on them. There is no shortcut that avoids paying for planks, and no alternative materials that replace them. If you have the correct logs and enough coins, you can always make planks the same way. Understanding this early saves a lot of confusion and wasted time.

How Plank Creation Works in OSRS

Planks are created by converting unnoted logs into planks through a sawmill operator, a servant, or the Plank Make spell. The conversion is instant, always succeeds, and charges a fixed amount of coins per log. Your levels, location, and equipment do not change the cost or output. All plank making methods follow this same rule set.

Plank Types Used for Construction

Only a specific set of logs can be turned into planks. Any log not listed here cannot be used for Construction.

Normal planks made from logs
Oak planks made from oak logs
Teak planks made from teak logs
Mahogany planks made from mahogany logs
Camphor planks made from camphor logs
Ironwood planks made from ironwood logs
Rosewood planks made from rosewood logs

Logs such as maple, yew, or magic do not have plank versions and cannot be converted.

Plank Conversion Costs

All sawmills charge the same prices, regardless of location.

  
      Plank Type
      Log Required
      Cost Per Plank
    
      Normal plank
      Logs
      100 coins
    
      Oak plank
      Oak logs
      250 coins
    
      Teak plank
      Teak logs
      500 coins
    
      Mahogany plank
      Mahogany logs
      1,500 coins
    
      Camphor plank
      Camphor logs
      2,500 coins
    
      Ironwood plank
      Ironwood logs
      5,000 coins
    
      Rosewood plank
      Rosewood logs
      7,500 coins

Coins and unnoted logs must both be in your inventory when converting planks.

Sawmill Locations

Every sawmill produces planks the same way, so location choice is about banking speed and movement.

  
      Sawmill Location
      Requirements
      Why Use It
    
      Lumber Yard near Varrock
      Members
      Default early game option, easy access
    
      Woodcutting Guild
      60 Woodcutting
      Bank next to sawmill, very smooth plank processing
    
      Prifddinas
      Song of the Elves
      Good for converting nearby teak or mahogany logs
    
      Auburnvale
      Area access
      Bank

Plank output and cost never change based on location.

Increasing Planks Per Hour

Efficiency comes from carrying more logs and planks per trip, not faster conversion.

Log basket increases the number of logs you can carry
Plank sack increases the number of planks you can carry
Using both together allows up to 54 planks per trip

Some players also use a looting bag at the Lumber Yard to store extra planks before banking. This is situational and mainly used for normal or oak planks.

Making Planks Inside Your House

After unlocking a servant such as a butler or demon butler, planks can be made from inside a player owned house. You bring unnoted logs into the house and send the servant to the sawmill to convert them. The coin cost per plank stays the same, but travel time is greatly reduced.

This method is commonly used for high level Construction training. If logs are noted, Phials can be used to unnote them efficiently.

Using the Plank Make Spell

The Plank Make spell converts logs into planks without visiting a sawmill. It requires 86 Magic and completion of Lunar Diplomacy and Dream Mentor. This method replaces travel time with rune costs and manual casting.

It is mainly used for convenience rather than saving gold.

Free Plank Sources

A limited number of planks spawn in the world and can be collected for free. These are mostly useful at very low Construction levels.

A teak plank spawn can also be collected using Telekinetic Grab after completing Song of the Elves, but this method is slow and not practical for large quantities.

Final Notes

Plank making in Old School RuneScape follows strict, predictable rules. Costs never change, conversion never fails, and efficiency always comes from movement and inventory management. Once you understand that planks are the true cost behind Construction, planning the skill becomes straightforward instead of frustrating.
