    Could you please share the form ID or form direct link so we can check it further? We can provide you a Custom CSS Code to change the size in the screenshot that you have provided. 

    We'll wait for your response.

    If you want to adjust the width of the textbox on your matrix field, you will need to inject custom CSS code to your form. Here is a sample CSS code that sets the matrix field width:

    td.form-matrix-values input {

        width: 100px;



    To inject custom CSS code to your form, just follow the instructions provided in this article: How to Inject Custom CSS Codes. If you are referring to a different concern, please provide us more details so we can further check your concern.
