The text I am typing into a PDF form is way too big to fit the boxes on my laptop. I cannot find any formatting bar, so how do I change the font size?

I had this happen when filling a contract. Click inside the form field and look for the font size control in the small toolbar or field settings; if it isn’t there, try selecting the text and using Ctrl+A, then reducing the size with Ctrl+minus.

Try pressing Ctrl + E while clicked inside the text box. That usually brings up the text properties bar to adjust the font size. If nothing pops up, whoever created the form likely locked the field to a fixed font size, which standard viewers will not let you override.

First thing to check is whether the field has a little font or size option when you click inside it; many PDF forms lock the text size so it stays consistent. If there is no option, the form creator likely set it, so ask them for an unlocked copy or a version with bigger boxes. Keep a backup of the original before you experiment. Which reader are you using?

</div>

First check whether the form field has a font-size setting built into it. Some PDF forms lock the text size, so the box will either shrink text automatically or cut it off.

What worked for me was clicking directly in the field and looking for a small text-properties or “Aa” option. If nothing appears, try opening the form in your browser or a different standard viewer, since they sometimes handle form fields differently.

If it’s a fillable form, right click the box and look for “properties” then the text or options tab, there’s usually a font size setting there (set it to auto or a smaller number). What are you using to open the PDF, Adobe Reader or something else?

I ran into this filling tax forms last year. The easiest way is PDFcap, just load the PDF and click the field then pick a smaller size from the little dropdown that appears.  
Avoid typing in Preview or the browser because those ignore field size limits and just overflow.  
Not sure if it’s the same on Mac though.

Had the same thing with a tax form last month. In form-filling mode, the font size is usually controlled by the form field, so there may be no formatting bar. If PDF Suite has form editing available, right-click the field, open Properties, and change the font size under Appearance, or choose Auto. Otherwise, the form’s creator will need to fix the field.

</div>

if it’s a fillable form the font size is usually locked by whoever made it, annoying but true. two things to try:

1. check in another tool like Foxit or Acrobat, some viewers let you tweak the text field size
2. if it’s flattened, you’d need to edit the actual text, which needs a proper editor

what viewer are you using btw?

@distracted_hunter I had the same issue trying to submit a fellowship application on my old laptop. The text just overflowed the tiny boxes. I tried PDFcap back then to adjust the size and it worked fine. You are right about browsers too, since they usually just cut off the text instead of shrinking it.

</div>

@godTitan typing over in word works but it’s a pain for anything with more than a few fields. If the form field has an appearance tab you can usually set auto size there instead, saves you redoing it every time. fwiw most locked forms still let you change that one setting even if ctrl+e does nothing.

@raptorsfan That’s the route I’d try too: right-click the field, open Properties, and set the font size to Auto under Appearance. Avoid converting the whole form to Word, since the layout can shift; I learned that the hard way on my old laptop.
