A 2.5 oz candle is relatively small in size compared to standard candles but is perfect for personal use or smaller spaces like bedrooms or office desks. The exact dimensions may vary depending on the brand or style of the candle; however, it is typically around 2 inches in diameter and 2-3 inches in height. Despite being compact in size, a 2.5 oz candle can still provide several hours of burn time, making it ideal for those who enjoy occasional moments of relaxation or prefer experimenting with different scents without committing to larger candle sizes.
