IMPACT
m m
abcdefghijklmnopqrstuvwxyz IMPACT Impact is a San-Serif typeface with a continuous construction which is the same with Helvetica. For this letter in impact the arches have quite an irregular, thin shape and the stems are very black and parallel giving the overall face a high contrast.The letter in Helvetica however is much lighter in appearance and a much lover contrast. Due to impact being black in colour, the letter appears ‘squashed’ and overall the typeface appears condensed, while Helvetica is much lighter and has a more regular weight and proportions. The terminations are sans-serif and almost always at a 90 degree angle a characteristic that is shared with Helvetica. The x-height of Impact is much larger than in Helvetica causing it to sit much heavier on the page. I would recommend using Impact for titles and perhapse subtitles if used in lower-case.
