What Is an SMS Character Counter?

An SMS character counter is a tool that counts the number of characters in a text message and calculates how many SMS parts it will use. It detects GSM‑7 and Unicode encoding, helping you avoid message truncation and unexpected costs. Ideal for marketing campaigns, customer support, and developers who need precise SMS segmentation.

How SMS Character Limits Work

GSM‑7 uses 160 characters per single SMS (153 for multipart). Unicode uses 70 per SMS (67 for multipart). Emojis and many non‑Latin scripts force Unicode, reducing capacity. Multipart messages are concatenated on the recipient’s device.
