Some digital versions of Bodoni are said to be hard to read due to "dazzle" caused by the alternating thick and thin strokes, particularly as the thin strokes are very thin at small point sizes. This is very common when optical sizes of font intended for use at display sizes are printed at text size, at which point the hairline strokes can recede to being hard to see. Versions of Bodoni that are intended to be used at text size are "Bodoni Old Face", optimized for 9 points; ITC Bodoni 12 (for 12 points); and ITC Bodoni 6 (for 6 points).
