Yes—many cities do use bins at different heights, especially where accessibility is a priority. Typical public bins often have openings around 36–42 inches high, but accessible models may have a lower opening, sometimes around 30–36 inches, a side door, or a dual-height design so wheelchair users, children, and shorter adults can reach them comfortably. Some fixed bins are retrofitted with lower flaps, while newer streetscapes may include one standard bin and one lower bin.
The best designs also keep the approach clear, use light-force push flaps or foot pedals, and avoid heavy lids or sharp edges. That said, not every city gets this right, and older bins can be too high or hard to operate. So the short answer is yes—height variation exists, but the quality and consistency vary by location.
