UI Design Best Practices

Learn how to create professional, good-looking user interfaces in Roblox with Revix.

UI Design Fundamentals

Hierarchy and Layout

Good UI design starts with clear hierarchy:

• Important elements should be larger and more prominent

• Group related elements together

• Use consistent spacing between elements

• Leave breathing room (whitespace) around content

Color Guidelines

Choose a Color Palette

Pick 2-4 colors that work well together:

• Primary color: Main buttons and important elements
• Secondary color: Backgrounds and secondary actions
• Accent color: Highlights and notifications
• Neutral colors: Text and borders

Color Contrast

Ensure text is readable:

• Dark text on light backgrounds
• Light text on dark backgrounds
• Minimum contrast ratio of 4.5:1 for normal text

Typography

• Use consistent fonts throughout your UI
• Limit font sizes to 3-4 different sizes
• Recommended fonts: GothamBold, GothamMedium, Gotham (modern look)
• Text sizes:

- Titles: 24-32px

- Body text: 14-18px

- Small text: 10-12px

Roblox UI Best Practices

ScreenGui Settings

{
  "ResetOnSpawn": false,
  "IgnoreGuiInset": true,
  "ZIndexBehavior": "Enum.ZIndexBehavior.Sibling"
}

Frame Sizing with UDim2

Use scale values (0-1) for responsive design:

{
  "Size": {"XScale": 0.3, "XOffset": 0, "YScale": 0.4, "YOffset": 0}
}

Use offset values for fixed sizes:

{
  "Size": {"XScale": 0, "XOffset": 200, "YScale": 0, "YOffset": 50}
}

Centering Elements

Center an element by setting:

• Position: {XScale: 0.5, YScale: 0.5}
• AnchorPoint: {X: 0.5, Y: 0.5}

Rounded Corners

Add UICorner for modern rounded look:

{
  "CornerRadius": {"Scale": 0, "Offset": 8}
}

Shadows and Depth

Create depth with:

• Multiple layered frames
• Subtle transparency differences
• UIStroke for borders

Common UI Patterns

Buttons

Good Button Design:

• Clear, readable text
• Sufficient padding (at least 12px all around)
• Rounded corners (8-12px)
• Hover and press states
• Consistent sizing

Example Button Properties:

{
  "Size": {"XScale": 0, "XOffset": 160, "YScale": 0, "YOffset": 48},
  "BackgroundColor3": {"R": 0, "G": 170, "B": 255, "fromRGB": true},
  "TextColor3": {"R": 255, "G": 255, "B": 255, "fromRGB": true},
  "Font": "Enum.Font.GothamBold",
  "TextSize": 18,
  "BorderSizePixel": 0
}

Cards/Panels

Good Card Design:

• Consistent padding inside
• Subtle background color
• Rounded corners
• Optional shadow/stroke

Example Card Properties:

{
  "BackgroundColor3": {"R": 30, "G": 30, "B": 40, "fromRGB": true},
  "BackgroundTransparency": 0.1,
  "BorderSizePixel": 0
}

Health Bars

Good Health Bar Design:

• Clear fill vs background contrast
• Smooth animations when changing
• Optional text label showing exact value

Inventory Grids

Good Grid Design:

• Consistent item sizes
• Clear selection indicators
• Hover effects for interactivity
• Scrolling for many items

Layout Components

UIListLayout

Auto-arrange children in a list:

{
  "Padding": {"Scale": 0, "Offset": 8},
  "FillDirection": "Enum.FillDirection.Vertical",
  "HorizontalAlignment": "Enum.HorizontalAlignment.Center"
}

UIGridLayout

Auto-arrange in a grid:

{
  "CellSize": {"XScale": 0, "XOffset": 100, "YScale": 0, "YOffset": 100},
  "CellPadding": {"XScale": 0, "XOffset": 10, "YScale": 0, "YOffset": 10}
}

UIPadding

Add internal padding to frames:

{
  "PaddingTop": {"Scale": 0, "Offset": 12},
  "PaddingBottom": {"Scale": 0, "Offset": 12},
  "PaddingLeft": {"Scale": 0, "Offset": 12},
  "PaddingRight": {"Scale": 0, "Offset": 12}
}

Animation and Polish

Smooth Transitions

Use TweenService for:

• Button hover effects
• Panel open/close animations
• Health bar changes
• Notification popups

Feedback

Provide visual feedback for:

• Button clicks (slight scale or color change)
• Form validation (green/red borders)
• Loading states (spinners or progress bars)
• Success/error states

Mobile-Friendly Design

Touch Targets

• Minimum button size: 44x44 pixels
• Adequate spacing between tap targets
• Avoid hover-only interactions

Responsive Scaling

Use scale values to adapt to different screen sizes:

• Test on both mobile and desktop
• Consider using different layouts for mobile

Safe Areas

Account for device notches and status bars using IgnoreGuiInset appropriately.

Common Mistakes to Avoid

• Too many colors - Stick to your palette

• Inconsistent spacing - Use consistent padding and margins

• Text too small - Ensure readability on all devices

• Cluttered layout - Leave whitespace for breathing room

• No visual hierarchy - Make important elements stand out

• Ignoring accessibility - Ensure sufficient color contrast

• Hardcoded sizes only - Use scale for responsive design

Asking Revix for UI Help

When requesting UI from Revix, be specific about:

• Purpose: "Create a shop UI for buying weapons"

• Style: "Modern, dark theme with blue accents"

• Layout: "Grid of items with prices and buy buttons"

• Functionality: "Clicking buy should fire a RemoteEvent"

Example Request:

"Create a modern-looking inventory UI with a dark theme. It should have a grid of 6x4 item slots, each slot should show an item icon and count. Include a close button in the top right corner. Use rounded corners and subtle shadows for depth."

This gives Revix all the context needed to create exactly what you want.
