What is the biggest problem caused by too little negative space in poster design?

Correct answer: Reading clarity will reduce

The direct answer is A: reading clarity will reduce. Negative space is the empty or relatively quiet area around and between words, images, and shapes. It gives the eye room to separate elements. In a poster, the reasoning is simple: if empty space is reduced too much, words and pictures become crowded; crowded elements compete for attention; the viewer needs more effort to identify the message; therefore reading clarity decreases. Option A is correct because insufficient negative space harms legibility and visual organisation. Option B is wrong because empty-space quantity does not always make colours light. Option C is wrong because a crowded layout does not automatically make a form more three-dimensional. Option D is wrong because printed or drawn texture does not become physically real merely because space is reduced. Negative space is not wasted space; it supports hierarchy, balance, and readability. The exam cue is: too little negative space usually means crowding and poor legibility.
