Is my gap too large to be closed with Invisalign? (photo)

Certainly any gap can be closed with
Invisalign. It’s just a matter of time and the process. The bigger the teeth
and provided you are comfortable with having attachments on these teeth, you
will be able to close that gap. Braces might work marginally faster but I guess
it’s a decision you have to make but certainly a skilled Invisalign clinician
with the right settings and the right use of the program can achieve a desired
result for you.

You should be able to have your space closed with
Invisalign. You also appear to have access of gingival tissue currently present
between your front two teeth so you might also need to consult a dentist regarding
a possible removal of that in conjunction with space closure.

From the photo you have sent us it does appear that you can close the space that you have.  You are correct that it is large but you can move the space a little further back and close the one in the front.  I would speak to a qualified invisalign dentist in your area to discuss your option
