# Fix: Shape is Too Big
## The Problem | Shape is Bigger than Block
A common error that throws off your fabric calculations is when a shape in your block is larger than the finished block.
Sometimes this is intentional - perhaps you can only make a shape by trimming it later. But most of the time this is unintentional and the PreQuilt Fabric Calculator will give you calculations for the entire shape, even if it's hidden from the final quilt block.
This often results in being told you need more fabric than you do.

### The Problem
In this example, the Sashing is throwing an Error Warning in the Fabric Calculator.
### Problem Analysis
Let's investigate what is causing the error. To do this:
{% stepper %}
{% step %}
In the design application, click on **Edit Block** for the Sashing quilt block.
{% endstep %}
{% step %}
Click on the **shape** in the block editor area.
{% endstep %}
{% step %}
Click on the **SIZE tab** on the left side control panel.
{% endstep %}
{% step %}
Once expanded, we can see that the width of the shape is larger than the finished block. You can see that it's at 150%, when it should be at 100%.
{% endstep %}
{% endstepper %}
### Fix the Error & Fabric Calculations
{% stepper %}
{% step %}
In the design application, click on **Edit Block** for the Sashing quilt block.
{% endstep %}
{% step %}
Click on the **shape** in the block editor area.
{% endstep %}
{% step %}
Click on the **Scale to Fit** button () on the center vertical toolbar.
{% endstep %}
{% step %}
Click on the **Save to Quilt** button in the top right corner.
{% endstep %}
{% step %} **Save** the quilt () and click on the **Fabric Calculator** button ().
{% endstep %}
{% step %}
The error is now gone and the fabric calculations are corrected.
{% endstep %}
{% endstepper %}
