how to reduce the size of checkbox

i would like reduce the size of the checkbox so that the checkbox square has the same size of text (F1X-Lab...) which is a listbox

You will probably need some tricks to find out how many lines would fit in your listbox, but then you can just change the Position property of your checkboxes.

But a more fundamental question: if you want to relate the checkboxes to your listbox items, why not make the elements the text for each checkbox? That would save you the trouble of alligning them.

with uitable, the text and the checkbox are ailgned but if i'll do that i loose the ability to select the element included in the text. the aim is double : in a listbox, select the different elements and make processing and in the checkbox select other elements (can be the same but not always) to visualize them

This will not work realiably. Even the OS can change the sizes of specific GUI elements. Use an uitable instead, (see Fabienne's comment) or an undocumented treeTable: https://undocumentedmatlab.com/blog/treetable
