TikTok Slideshow Size: 9:16 Photo Slides, Explained in 5 Minutes

By Manol TThe quick answerIf you want the right TikTok slideshow size for photo slides, start with a vertical 9:16 canvas. The figure most people cite is 1080 by 1920 pixels. That matches the full phone screen, so your slides fill the frame instead of sitting in a box.One caution up front: apps change. The numbers on this page are commonly cited, not guaranteed. Check the current in-app guidance before you build a big batch.Why TikTok slideshow size is verticalTikTok is a full-screen, upright feed. A slide that is square or wide will show with empty bars or get cropped to fit. A 9:16 slide uses the whole screen, which gives you the most room for a photo plus a headline.Set up one templateMake a single blank canvas at 1080 by 1920 and save it as your master. Every slide should be a copy of it. This keeps your dimensions identical from the first slide to the last, so nothing shifts when people swipe.Keep your original photos in a separate folder. Export the finished slides into their own folder. If you ever need to redo a slide, you will start from the untouched photo.Margins matter more than you thinkTikTok places buttons, captions and the account name over the video area. Slideshows are no different. Do not put anything important right at the edges. A simple rule:• Keep headlines away from the very top.
• Keep key words well above the bottom, where the caption and controls sit.
• Leave breathing room on both sides.Rather than guess, use a safe-zone overlay and place your text inside it.Landscape photos on a vertical canvasThis is where most people get stuck. If you stretch a wide photo to fill the height, you cut off both sides, and the subject can vanish. Better options:• Scale the photo to the width and use the space above and below for a headline or label.
• Crop on purpose around the main subject, instead of letting the app centre-crop.
• Use a plain background colour behind the photo so the slide looks designed, not cropped.One idea per slideA slideshow is read in order. Give each slide a single job: hook, point, point, point, next step. If a slide needs a paragraph, split it into two slides. Short text is also easier to keep inside the safe margins.Text sizeCheck your slides on an actual phone. If you have to lean in to read, the type is too small. Pick a headline size and a body size once, and use them on every slide.Pre-post checklist1. All slides have the same pixel dimensions.
2. Nothing important touches the edges.
3. The first slide makes sense by itself.
4. You have checked the current photo limit in the app.
5. Your caption adds context and does not repeat the slides word for word.
6. You own or have permission to use every photo.Where to check the numbersWe keep a reference with the commonly cited dimensions and limits for photo carousels.
