Storyboard Composer
Print a ready-to-sketch storyboard in 16:9, 9:16, square or 4:3, with your shot list already filled in below each frame.
Description | Audio or dialogue | Duration. All three are optional — a bare description works fine on its own.About this storyboard composer
A storyboard exists to answer one question before you shoot or animate a single frame: does the sequence actually work? A blank rectangle for each shot, in the right aspect ratio for where the finished thing will actually play, forces that question early — while it is still a five-minute sketch, not a re-shoot.
Pick the frame shape to match your platform: 16:9 for YouTube and traditional widescreen video, 9:16 for Reels, TikTok and Stories, square for a feed post, or 4:3 for older or classic-styled footage. Each frame prints as a blank box in the correct proportions, ready to sketch in by hand, with a numbered slot and space underneath for a description, audio or dialogue notes, and duration.
The shot list is optional and works either way. Leave it blank for a completely empty template — useful when you plan to sketch and write everything by hand while the idea is still forming. Or type your shots in advance, one per line as Description | Audio or dialogue | Duration, and the notes underneath each frame arrive already filled in, leaving just the sketch itself to do by hand. All three fields are optional on each line, so a plain one-word description is just as valid as a fully detailed line.
Frames per row is yours to set, and the tool works out how many rows actually fit — tall 9:16 frames typically fit only a single row at a readable size, while wide 16:9 frames comfortably stack two or three rows on the same page, which is simply a consequence of the shapes involved rather than a limitation of the tool. If your shot list is longer than one page holds, print a second sheet for the rest.

Frequently asked questions
Which frame shape should I use?
Match wherever the finished video will actually play: 16:9 for YouTube or standard widescreen, 9:16 for vertical formats like Reels, TikTok and Stories, square for a feed post, and 4:3 only if you are deliberately working in an older or classic format.
Why does 9:16 only fit one row of frames?
A vertical frame is naturally tall, so at a readable size it takes up most of the page's height on its own. This is a consequence of the aspect ratio itself, not a limitation of the tool — 16:9's short, wide frames comfortably stack two or three rows on the same page instead.
Can I type my shots in advance instead of sketching everything cold?
Yes — use the shot list box, one line per frame as Description | Audio or dialogue | Duration. Any of the three can be left out; the notes under each frame fill in with whatever you provided, leaving the visual box itself for sketching.
My shot list is longer than the page holds
The tool tells you how many shots fit and how many are left over. Add more frames per row if the aspect ratio allows it, or print a second sheet for the remaining shots.
My frame borders are not printing
Look for a "Background graphics" or "Print backgrounds" option in your print dialog and switch it on — some browsers strip borders and fills from printed pages by default.
