BRP Social Media Guide
This guide summarizes recommended image dimensions and text length limits for all major social platforms supported in Zoho Social, so Blue Ribbon Project staff and volunteers can prepare posts correctly for each channel.
How to Use This Guide
This page outlines the most common image sizes and character limits for posts on each platform listed in the December 2025 Hootsuite image size guide, along with basic recommendations for Blue Ribbon Project content.
Staff and volunteers can reference this when drafting posts and selecting or creating images, then remove platforms that BRP does not actively use from the final Joomla article.
General Standards for BRP Posts
All content must use calm, trauma-informed language that centers dignity and safety for children, survivors, and families, without graphic or sensational details.
Images should feature BRP events, volunteer activities, and community outreach that are suitable for public viewing, without identifying individual children or disclosing private information.
- Use clear, plain language with a focus on support, education, prevention, and available resources.
- Avoid sharing identifying details about children, survivors, or specific cases in any public post.
- When in doubt, link to a resource page on the BRP website for fuller context instead of posting detailed explanations directly to social media.
Facebook is useful for longer educational posts, event promotion, and sharing BRP resources with the community in a conversational tone.
Posts should be concise, but Facebook allows more characters than most networks, so short summaries plus a link to the BRP site are often effective.
- Post character limit: Up to approximately 63,000 characters, though posts perform best under 80–120 characters for the main message.
- Recommended image sizes (feed): Square 1080×1080 px; vertical 1080×1359 px; landscape 1080×566 px.
- Stories: 1080×1920 px vertical (9:16), keeping key text away from the very top and bottom where interface elements may overlap.
Instagram emphasizes visual storytelling, with a grid that crops posts vertically, so images should be high quality and composed for vertical display.
Captions can be up to 2,200 characters, but only the first lines are visible without tapping “more,” so important points should come first.
- Post/Feed image sizes: Square 1080×1080 px; vertical 1080×1350 px (recommended); landscape 1080×566 px.
- Stories and Reels: 1080×1920 px vertical (9:16), with important content kept within a central safe area away from edges.
- Caption character limit: Up to 2,200 characters per post.
X (formerly Twitter)
X works best for brief announcements, quick updates, and linking to longer resources on the BRP site.
The default character limit for standard accounts remains focused on short text, so messages should be clear and direct.
- Post character limit: 280 characters for standard posts, with higher limits available only on certain paid tiers.
- Recommended image sizes: Landscape 1280×720 px; square 720×720 px; vertical 720×1280 px.
- Best practice: Aim for under 200 characters so reposts and comments remain readable and easy to share.
LinkedIn is a professional platform for sharing BRP updates with partners, agencies, and community organizations.
Posts can be longer than on X, but clear, skimmable paragraphs and strong first lines are still important.
- Post character limit: Up to around 3,000 characters in a standard status update.
- Recommended image sizes (feed): Landscape 1200×627 px; square 1200×1200 px; vertical 720×900 px.
- Best practice: Lead with one or two sentences summarizing the key takeaway or call to action.
TikTok
TikTok focuses on short, vertical video with optional short captions and can be useful for awareness messages if used carefully and non-graphically.
Even though the content is video, the cover frame and any overlaid text need to be readable and safe for all audiences.
- Video size: 1080×1920 px vertical (9:16) is recommended for standard posts.
- Caption character limit: Up to about 2,200 characters, though short, focused captions are more effective.
- Best practice: Keep on-screen text minimal and avoid including sensitive details in video audio or text.
Pinterest can serve as a visual resource board, highlighting educational graphics, blog posts, and supportive content from BRP.
Pins are primarily vertical images with space for a title and description.
- Pin image size: Recommended 1000×1500 px (2:3 aspect ratio) for standard pins.
- Pin title: Up to about 100 characters, with roughly 40 characters commonly visible.
- Pin description: Up to around 500 characters; aim for straightforward, keyword-rich summaries.
YouTube
YouTube is primarily video-focused, but BRP content will still rely on properly sized thumbnails and concise text for titles and descriptions.
Thumbnails need to be clear and readable at small sizes without graphic or distressing imagery.
- Thumbnail size: 1280×720 px (16:9), with a minimum width of 640 pixels.
- Video title: Up to 100 characters, with shorter titles under about 70 characters displaying better.
- Description: Up to 5,000 characters, though only a portion shows above the “more” fold.
Bluesky
Bluesky is a short-text social platform similar to early Twitter, with a moderate character limit for posts.
Posts should be concise and link back to BRP resources when more context is needed.
- Post character limit: Around 300 characters per post on most instances.
- Image guidance: Longest side at about 1000 pixels; use standard aspect ratios such as 1:1, 4:5, or 9:16 for best results.
- Best practice: Keep one clear idea per post with a single link or call to action.
Threads
Threads supports slightly longer posts than X and is closely tied to Instagram, with an emphasis on casual but thoughtful conversation.
Posts work well as single, complete thoughts rather than long threads, with optional images attached.
- Post character limit: Around 500 characters for standard posts, with higher limits available in some newer formats.
- Recommended image size: 1440×1920 px vertical; other standard aspect ratios are accepted and auto-adjusted.
- Best practice: Lead with a clear, supportive statement, then add a link to a BRP resource if needed.
Google Business Profile
Google Business Profile posts help highlight key BRP updates, events, and resources directly in Google Search and Maps.
Posts are relatively short and should focus on one clear action, such as learning more, registering, or contacting BRP.
- Post description limit: Up to 1,500 characters per post, with an ideal length of about 100–300 characters for mobile display.
- Recommended post image size: 1200×900 px (4:3 aspect ratio) for standard post photos.
- Profile and cover images: Logo images typically use square formats (for example, 720×720 px), and cover photos commonly use a 16:9 ratio such as 1024×576 px.
Mastodon
Mastodon is a federated social platform where BRP can share short updates, resource links, and event information in a calm, non-sensational tone.
The default software supports short posts, but individual servers can increase limits, so BRP should aim for readable, concise updates.
- Post character limit (default software): 500 characters, though some servers raise this higher; BRP posts should generally stay under this length unless a specific server configuration allows more.
- Images: Mastodon commonly accepts standard social media image ratios, such as 1:1, 4:5, and 16:9, with recommended widths of at least 800–1200 px for clarity.
- Best practice: Share one focused message per post with a link to a BRP resource page for full details.
Other Platforms (Optional)
If BRP adopts additional platforms in the future, staff can follow the same pattern: confirm the current recommended image size and post character limit, then define a trauma-informed, supportive visual approach.
Any platform that emphasizes disappearing content or anonymous interaction should be used cautiously, with a focus on brief, resource-oriented messages rather than detailed stories.
- Always prioritize safety, privacy, and dignity over reach or engagement metrics.
- Periodically review platform documentation to confirm that image sizes and character limits have not changed.
