# Texel Size Node
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
Returns the **Width** and **Height** of the texel size of **Texture 2D** input. Uses the built in variable `{texturename}_TexelSize` to access special properties of a **Texture 2D**.
|
||
|
|
|
||
|
|
If you experience texture sampling errors while using this node in a graph which includes Custom Function Nodes or Sub Graphs, you can resolve them by upgrading to version 10.3 or later.
|
||
|
|
|
||
|
|
**Note:** Do not use the default input to reference your **Texture 2D**. It makes your graph perform worse. Instead connect this node to a separate [Texture 2D Asset Node](Texture-2D-Asset-Node.md) and re-use this definition for sampling.
