You can do a binary search for the maximum size, something like (in python3)

def maxFontSize(s):
  low = 1
  high = 30
  while low <= high:
    mid = (low + high) // 2
    h = getCharacterHeight(mid)
    if h > H:
      high = mid - 1
      continue

    for c in s:
      w += getCharacterWidth(c, mid)
   if w > W:
      high = mid - 1
   else:
      low = mid + 1
  
  return (low+mid) // 2

binary search recursively:

def maxFontSize(s,W,H,left,right):
    if right<left:
        return right
    mid=(left+right)//2

    h=getCharacterHeight(mid)
    w=0
    for c in s:
        w+=getCharacterWidth(c,mid)

    if h==H and w==W:
        return mid
    if w>W or h>H:
        return maxFontSize(s,W,H,left,mid-1)
    if w<W or h<H:
        return maxFontSize(s,W,H,mid+1,right)

s="string"
size=maxFontSize(s,W,H,0,30)
if size==0:
    print("'{s}' is too large for the dimensions of the rectangle".format(s=s))
else:
    print("size {size} is the largest font size for the rectangle".format(size=size))
