YouTube Membership Emoji Size Guide: Dimensions, Limits & Design Tips

Planning to set up custom emojis for your YouTube channel memberships? Getting the size wrong means blurry emojis, rejected uploads, or designs that look great on your screen but turn into unreadable blobs in chat.

This guide covers every technical requirement straight from YouTube's official documentation, plus practical design tips from creators who've been through the approval process.

Emoji Dimensions Explained

YouTube accepts emoji images between 32x32 and 512x512 pixels, but the recommended upload size is 48x48 pixels. Here's why that number matters:

• 32x32 px — The minimum. YouTube won't upscale your image, so this is what users see on standard displays. Acceptable but may look soft on Retina screens.
• 48x48 px (recommended) — Matches the native display size on HiDPI/Retina screens. This gives you the crispest result across all devices without unnecessary file bloat.
• Up to 512x512 px — YouTube will downscale larger images. Uploading at a higher resolution doesn't improve quality since the display size is capped. It just means a larger file.

Always design at 48x48 pixels or use a multiple (96x96, 192x192) and scale down. Designing at odd sizes like 100x75 will result in distortion when YouTube forces it into a square.

File Format & Size Requirements

YouTube supports three file formats for custom emojis, but they're not equally useful:

PNG is the clear winner. Transparent backgrounds mean your emoji adapts to both YouTube's light and dark themes. JPEG forces a solid background, and GIF loses its animation entirely.

File Size

Each file must be under 1 MB. At 48x48 pixels, a PNG is typically 2–10 KB — you won't hit this limit unless you're uploading a much larger source image. If you are bumping into the limit, re-export at 48x48 directly instead of scaling down from a massive canvas.

How Emojis Display Across Devices

Your 48x48 emoji won't always display at 48 pixels. YouTube scales emojis differently depending on where they appear:

At 14–16 pixels, fine details like thin text, gradients, and small facial features become invisible. Always preview your emoji at 16x16 before uploading.

Emoji Slots by Membership Tier

You don't get unlimited emoji slots right away. YouTube gradually unlocks more slots as your channel membership count grows. Here's how the tier system works:

Use the calculator below to check exactly how many emoji slots your channel currently has and how many members you need for the next unlock:

With only 4 slots to start, pick your most iconic emojis first. You can always add more as you grow. Many creators start with: a greeting emoji, a hype/excitement emoji, a love emoji, and their channel logo.

Naming Rules & Family Names

YouTube uses a family name + emoji name system. Your family name is a shared prefix for all your channel's emojis, and each emoji gets its own unique name within that family.

Family Name Rules

• Must be 3–10 characters long
• Alphanumeric only (letters and numbers, no spaces or special characters)
• Should relate to your channel brand or name
• Difficult to change once set — choose carefully

Individual Emoji Name Rules

• Must be 3–10 alphanumeric characters
• Must be unique within your family (but can overlap with other channels)
• Members type the emoji as :familynameemojiname: in chat

For example, if your family name is "pixel" and you name an emoji "heart", members type :pixelheart: to use it. Keep names short and intuitive — your members need to remember and type them quickly during live chat.

Good family names: "cozy" (4 chars), "apex" (4 chars), "storm" (5 chars). Bad family names: "ab" (too short), "mysupercoolchannel" (too long), "my_name" (underscores not allowed).

Design Tips for Tiny Emojis

Designing at 48x48 pixels is a unique challenge. What looks great at full size often becomes an unreadable mess in live chat. Here are battle-tested tips from creators:

1. Use Bold, Simple Shapes

Stick to large, recognizable shapes with clear silhouettes. A chunky heart reads much better than a detailed rose at 16 pixels. Think emoji-level simplicity, not illustration-level detail.

2. Limit Your Color Palette

Use 3–5 strong colors maximum. Subtle gradients disappear at small sizes. Flat colors with clear boundaries between elements work best. Choose saturated, vibrant colors that pop against both light and dark backgrounds.

3. Add a 1px Border for Visibility

Adding a thin outline in a contrasting color (white or dark gray) ensures your emoji stays visible regardless of the chat background color. This is especially important for emojis with dark or transparent elements.

4. Test at Actual Display Size

Before uploading, zoom your browser to 100% and look at the emoji at 16x16 pixels. If you can't instantly recognize what it is, simplify the design further. The "squint test" works well — squint at your design, and whatever is still recognizable is what viewers will see.

5. Consider the 8-Bit Pixel Art Style

Pixel art naturally works well at tiny sizes because it's designed for low-resolution displays. If your channel's brand allows it, this style guarantees sharp, readable emojis at any size.

How to Upload Your Emojis

Here's the step-by-step process to add custom emojis to your YouTube channel memberships:

1. Open YouTube Studio and go to Earn in the left sidebar
2. Click Memberships, then select Badges and Emojis
3. Click Edit to enter the emoji management interface
4. Set your family name (first time only — this applies to all your emojis)
5. Click an empty slot and upload your PNG file (48x48 px recommended)
6. Name each emoji (3–10 alphanumeric characters)
7. Click Save — YouTube will review within 24 hours

Eligibility Requirements

Before you can upload emojis, your channel must meet these requirements:

• You must be 18 years or older
• Your channel needs 1,000+ subscribers
• You must be in a supported country for memberships
• No active community strikes on your channel
• Channel memberships must be enabled in YouTube Studio

Membership Badge Sizes

Badges are the small icons that appear next to a member's name in chat and comments, showing their membership duration. They have slightly different requirements than emojis:

The 6 badge tiers correspond to membership duration: new member, 1 month, 2 months, 6 months, 1 year, and 2 years. You can create unique badges for each tier to reward long-term supporters with progressively fancier designs.

Summary

Getting your YouTube membership emojis right comes down to a few key rules:

• Upload at 48x48 pixels in PNG format with a transparent background
• Keep files under 1 MB (rarely an issue at 48x48)
• Design for 16px display — bold shapes, limited colors, no fine detail
• You start with 4 emoji slots, growing to 49 at 5,000+ members
• Choose a short family name (3–10 chars) — it's hard to change later
• GIFs are static on YouTube — animation is not supported
