> Quick answer: Lead with the offer, build a 1080 x 1350 px portrait creative, stay inside the safe zone, write urgent copy, and launch. All five steps below.
A discount ad that converts has three things: a clear offer, a clean visual, and a reason to act now. Follow these five steps and you will have a high-performing promo live on Instagram today.
What Makes a Discount Instagram Ad Effective
Per Meta's Best Practices for Instagram Image Ads, effective ads are visually-driven, brand-consistent, and concept-driven. For discount ads, that means one job: make the offer impossible to miss. A cluttered creative buries the deal. A clean, high-contrast image with the discount front and center wins every time.
Step 1: Choose Your Ad Format and Dimensions
Start with the right canvas. Wrong dimensions produce cropped assets and lower delivery quality.
Why 4:5 (portrait) works best
Portrait format takes up more vertical screen space in the Instagram Feed. More screen space means more attention. That is the entire argument.
Standard image specs: 1080 x 1350 pixels
Per Meta's Design Requirements for Instagram Feed Ads, the recommended image size is 1080 x 1350 pixels at a 4:5 aspect ratio. Use this as your default for any promo creative. The minimum width is 600 pixels, but 1080 px renders crisply on all devices.
Square format alternative: 1080 x 1080 pixels
Square (1080 x 1080 pixels) works if your product image is naturally square or you are repurposing existing assets. It is less dominant in the Feed than portrait, but still a solid choice.
Step 2: Design a Visually Focused Promo Creative
Your creative should answer one question in under two seconds: "What is the deal?"
Product showcase with minimal text overlay
Show the product clearly. Keep text short. Long copy on the image creates noise and hurts performance. One or two lines maximum.
Display discount prominently (% or $ amount)
Put the discount front and center. "30% OFF" in bold, high-contrast type. Do not make the viewer hunt for it.
Use high contrast and brand colors
Contrast draws the eye. Use your brand palette, but make the offer pop visually. A discount badge or sticker treatment works well here.
Keep essential content in safe zone (5-10% from edges)
Keep all key elements, including the offer, CTA, and logo, at least 5-10% away from every edge. Different devices crop differently. Content near the edge can disappear entirely.
Step 3: Craft Copy That Creates Urgency
Copy does the job the visual sets up. Lead fast.
Lead with the offer (20% off, limited time, etc.)
Start the primary text with the discount. "Get 20% off this weekend only." Do not bury the offer in sentence two. Per Social Media Examiner's analysis of Instagram ad performance, urgency and time-limited framing significantly increase click-through rates on discount ads.
Explain the benefit/value proposition
One sentence. What does the buyer actually get? "Free shipping on all orders over $50" or "Stock up before prices reset." Simple and specific beats clever and vague.
Add a clear call-to-action button
Match your CTA button to the action. "Shop Now" for product pages. "Get Offer" for promo code redemptions. Be direct.
Step 4: Highlight Your Promo Code (If Using One)
A promo code buried in a wall of text gets ignored every time.
Use line breaks to make codes stand out
Give the code its own line. Even better, its own paragraph. "Use code: SAVE20" on a standalone line is far more readable than code tucked into a sentence.
Avoid burying in caption text
Do not attach the code to a long sentence. Standalone formatting signals importance to the reader.
Use Meta's promotional ad tool for code activation
Meta's Promotional Ads tool allows discount codes to auto-apply at checkout. Per the Meta Help Center guide on highlighting promotions in Meta Ads Manager, this removes friction and lifts conversions. Set it up in Ads Manager under the "Promotion" section.
Step 5: Set Up and Launch Your Ad
With your creative and copy ready, the launch itself should be fast.
Select Instagram Feed as placement
Choose "Instagram Feed" under placements in Ads Manager. This ensures your 4:5 creative displays exactly as designed.
Target warm/cold audiences appropriately
Warm audiences, like retargeting website visitors or past buyers, respond well to a direct discount push. Cold audiences need more context first. Adjust your copy accordingly for each.

Frequently Asked Questions
What is the best image size for a discount Instagram ad?
The recommended size is 1080 x 1350 pixels at a 4:5 aspect ratio. This portrait format takes up more vertical space in the Feed and tends to get more attention than square or landscape formats.
How should I display a promo code in my Instagram ad?
Give the promo code its own line or paragraph in the caption. Standalone formatting makes it impossible to miss. You can also use Meta's Promotional Ads tool to auto-apply the code at checkout, which removes friction for buyers.
Does urgency really matter in discount ad copy?
Yes. Time-limited framing, such as 'this weekend only' or 'limited stock', creates a reason to act immediately rather than scroll past. Lead with the offer and the deadline in your first line of copy.
Can I use Coinis to create and launch discount Instagram ads?
Yes. Coinis's Sale Promo workflow generates discount ad creatives from your offer details. The Campaign Launcher then publishes the finished ad directly to Instagram and Facebook through Meta.
