Question 1166388
<font face="Times New Roman" size="+2">

Depends.  How far apart are the tacks spaced?  Is that the space between the edges of the head? (In which case you would also need to know the diameter of the head of a tack) Or is the spacing on centers?  Way too little information given to answer this question.
