The accuracy of a combination square depends on how well it is calibrated. To ensure accuracy, look for squares with etched markings rather than printed ones. You can also check reviews from other users to see if they have experienced any issues with accuracy.

Features

Some combination squares come with additional features such as spirit levels or scriber attachments. These features can be useful for more precise measurements but may also add to the overall cost. Consider whether these features are necessary for your projects before making a purchase.
