Mockup & App Store Visuals Guide

Thirty practical guides on device mockups, App Store and Google Play screenshot sizes, promo videos, camera moves and export settings — written by the people who build Mockuptop.

• App Store screenshot sizes, without the spreadsheetThe iPhone and iPad screenshot sizes App Store Connect accepts, how many you can upload, and why one size usually covers your whole listing.
• Google Play screenshot sizes and store graphicsPhone, tablet, feature graphic and icon dimensions for a Google Play listing, plus the aspect-ratio limits that quietly reject uploads.
• App preview videos: specs and a workable structureLength, resolution, frame rate and content rules for App Store app previews, plus how to plan a 20-second cut that still works muted.
• The Google Play promo video, and how to make it earn its slotHow the Play Store promo video works, why it is a YouTube link rather than an upload, and how to structure the first five seconds.
• Designing a feature graphic that survives being shrunkDesign rules for the Google Play feature graphic, including safe areas, text size and why the centre must stay clear.
• Putting a screenshot inside an iPhone mockupA step-by-step method for turning a plain screen capture into a device mockup, including sizing, corners and background choices.
• Android phone mockups for a Play listingHow Android device mockups differ from iPhone ones, which aspect ratio to design for, and how to keep a Play listing consistent.
• Laptop mockups that make a web app look realHow to present a web app in a laptop mockup: capture width, lid angle, shadows and when a flat browser frame beats a 3D one.
• Tablet mockups and why stores keep asking for themTablet screenshot sizes, landscape versus portrait, and why Play and the App Store treat tablet assets as a ranking signal.
• Smartwatch mockups: small screen, big framing problemHow to present a tiny screen convincingly: crop, scale, band choices and why watch mockups need different framing than phones.
• 3D device mockups, used deliberatelyThe difference between a flat mockup template and a real 3D render, and how to use perspective without hurting legibility.
• Device frame or plain screenshot: decide per placementWhen a device frame helps conversion, when it wastes pixels, and how to decide per surface rather than by habit.
• Writing captions for app store screenshotsHow to write and place the text on app store screenshots so it reads at thumbnail size and adds something the image cannot.
• Your first screenshot is doing most of the workWhy the opening image in a store carousel carries disproportionate weight, and how to choose and design it.
• A pre-flight checklist for store visualsA short pre-flight list for app store visuals: sizes, order, captions, localisation, consistency and the mistakes that get listings rejected.
• Localised screenshots without redesigning eleven timesHow to build a screenshot set that translates cleanly, which languages actually pay off, and the layout decisions that make localisation cheap.
• Light or dark: which theme belongs in your store listingWhether to present your app in light or dark mode, how the store background affects the choice, and how to show both without doubling the work.
• Choosing a background that keeps the screen the subjectHow to choose a background for a device mockup so the interface stays the focus, including gradient direction, contrast and brand colour use.
• Lighting a device mockup so it looks like an objectA practical three-light setup for device renders, why metal and glass go black, and how to place a contact shadow that grounds without dominating.
• Camera angles: five framings that cover almost everythingHow tilt, roll, field of view and zoom interact in a 3D mockup, and which framings keep the screen readable.
• Keyframes: the smallest possible working modelHow keyframe animation works in a mockup editor, which properties are worth animating, and how many keyframes a good shot actually needs.
• Easing is the difference between motion and movementWhat easing curves do, which ones suit product motion, and the specific mistakes that make a mockup video feel amateur.
• How a 20-second app promo is actually builtA shot-by-shot structure for a short product video, with timings, what each beat has to accomplish and where most attempts go wrong.
• Choosing an export format for a mockupWhich image format to export a mockup in for stores, websites and social, and how transparency and gradients change the answer.
• Exporting a mockup video that does not look compressedResolution, frame rate, bitrate and codec choices when exporting a mockup video, and why frame-by-frame export beats screen recording.
• Transparent mockups: useful everywhere except app storesExporting a device mockup with alpha, where transparency helps, and the places it will get your upload rejected.
• Using a mockup in a landing page heroHow to use a mockup on a landing page: size, cropping, static versus video, and keeping the page fast.
• Sizing product mockups for social platformsPractical aspect ratios for product mockups on X, LinkedIn, Instagram and Product Hunt, plus the safe-area rules that stop cropping disasters.
• Device mockups and the legal questions people skipThe practical rules around using device imagery in marketing — trademarks, photo licences, and why a neutral rendered device is the low-risk option.
• Turning a screen recording into a store-ready previewA complete workflow: capturing clean footage on device or simulator, trimming it, placing it in a mockup and exporting a store-ready preview.
