# 2115: Stimulus size is bigger than the window dimensions¶

## Synopsis¶

Your stimulus size exceeds the X or Y window dimensions. Stimuli sized greater than the window size will not be completely visible.

## Details¶

This issue is often caused by an inconsistency between the units of your stimulus and the values being requested. For instance a size of 3, when the units are deg is sensible (3 degrees would be within the screen dimensions) but a size of 3 when the units are height would not be sensible (3 times bigger than the height of the screen).

All versions.

## Solutions¶

Check the size and the :ref:units of the stimulus <units>_ carefully. You may also need to check the monitor calibration if you’re using units that depend on the monitor size and resolution (like cm and deg).
