How long can an Instagram caption be?

Up to 2,200 characters, but only the first 125 show before the fold. Both lengths work: short captions keep attention on the Reel, long storytelling captions increase time-on-post. What never works is burying the hook below the fold.

How many hashtags should I use on Instagram?

Five to eight relevant tags is the current sweet spot: a mix of large tags for reach and niche tags where you can actually rank. The generator includes them automatically, matched to your topic. Putting hashtags in the first comment instead of the caption works the same for reach and keeps the caption clean.

What makes a caption perform on Instagram specifically?

Saves and shares. Instagram surfaces content people found useful or worth sending to a friend, which outweighs likes. Captions that add a tip, a list, or context worth returning to earn saves; captions with a relatable line earn shares. That is why IG captions can be longer and more substantial than TikTok ones.

Yes, generating captions is free and needs no account. If you also need the Reel itself, the same platform generates faceless Reels with AI voiceover, visuals and burned-in captions.

Frequently asked questions

Everything about writing Instagram captions

Put the hook in the first 125 characters, since that is all Instagram shows before the fold. Then either stop there (short and punchy works for Reels) or tell a story that earns the 'more' tap. End with a reason to save or share, which are the signals Instagram's algorithm weighs most. The generator produces ten variants across these styles so you can pick the one that fits.
