Installer window size is one of those details users only notice when it is wrong. Too small, and your layout feels cramped. Too large, and it becomes awkward on MacBook displays.
DMGKit gives you control over the installer window size while preserving the layout you created in the visual designer.
Why installer size matters
Different Macs have different display sizes, pixel densities, and scaling settings. Choosing a balanced installer size helps prevent clipping and keeps the install flow intentional.
Recommended presets
- Compact: 960 × 600 — safest for small displays.
- Small: 1120 × 700 — efficient and clean.
- Balanced: 1280 × 800 — recommended for most apps.
- Large: 1440 × 900 — useful for spacious layouts.
- Default canvas: 1600 × 1000 — best for full design work.
Best default choice
For most apps, start with 1280 × 800.
Recommended installer window size: 1280 × 800
Recommended design canvas: 1600 × 1000How scaling works
DMGKit scales layout proportionally so icon placement and spacing remain visually consistent.
- Background art scales with the export preset.
- Icon positions remain aligned.
- Relative spacing is preserved.
Testing checklist
- Mount the exported DMG on a laptop-size screen.
- Check icons are visible without scrolling.
- Confirm the arrow points clearly to Applications.
- Avoid critical elements near edges.
Ship cleaner Mac releases
Design, notarize, inspect, and distribute from one native workflow.
DMGKit helps developers turn a fragile release checklist into a polished, repeatable Mac distribution process.
FAQ
What installer size should I use?
1280 × 800 is a strong default for most polished DMG installers.
Can I use 1600 × 1000?
Yes, but it may feel large on smaller screens. It is better as a design canvas.
Does DMGKit preserve layout when changing size?
DMGKit is designed to preserve proportional layout positioning when changing installer resolution.
