Diwali Social Media Post Design: Ideas and a Day-by-Day Plan for Brands (2026)

Diwali is the biggest week of the year for brand pages in India. People are buying clothes, sweets, gifts, gold, electronics and things for the home, and they are scrolling more than usual. It is also the week when most brand pages look exactly the same, because they all start from the same free template: an orange background, a row of diyas and a logo in the corner.

I design festival posts for the Nepali calendar, including Teej and Vishwakarma Puja campaigns for two brand accounts this year, and Tihar, our festival of lights, falls in the same week as Diwali. I live in Biratnagar, right on the border with Bihar, so Diwali and Chhath are part of my own calendar too. This guide is the plan I would use for a brand page this year: the dates, the posts to make, the design ideas that stand out, and the technical details that stop a good design from looking broken on a phone.

Diwali 2026 dates for your content calendar

These dates follow most Indian panchang listings for 2026. Puja timings change by city, so check a local calendar before you schedule anything that mentions a muhurat.

A day-by-day posting plan

One greeting on the main day is not a plan. A short series spread over three weeks gives your audience time to notice the offer, and it gives your ads something to push.

1. Mid-October, three weeks out: a teaser. "Something is coming this Diwali" with a blurred product or a countdown sticker in your stories.
2. Two weeks out: launch the offer or the gift range. This is the creative you will run as an ad, so make it clear at a glance: product, one headline, one number.
3. One week out: a carousel. A gift guide, a "how to style it" or a "what's new this season" set of 4 to 6 slides.
4. Dhanteras: the strongest sales post of the week, plus stories with a link or a "message us" button.
5. Choti Diwali: a last-chance reminder with delivery or store timing.
6. Diwali morning: the greeting post and a reel version. Post early, when people are sharing wishes.
7. Bhai Dooj: a warm family post. Gifting brands can pair it with a small offer.
8. The week after: a thank-you post, ideally built from customer photos or messages you have permission to share. Then the Chhath greeting if your customers are in the east.

12 Diwali post design ideas that do not look like a template

The test for every idea below is simple: if you cover the logo, can people still tell which brand posted it? If not, the design is doing the festival's job, not yours.

1. Build the diya from your product. A tap, a lipstick, a sneaker sole, a coffee cup: shot or arranged so the flame sits on top of it. It is the fastest way to make a greeting unmistakably yours.
2. A rangoli made of your products. A top-down flat lay in a circular pattern. It works for food, cosmetics, jewelry, stationery and anything small.
3. Brand colors first, gold second. Keep your own palette as the base and use gold and warm light as accents. A blue or green brand that switches to full orange for one week loses its look.
4. Lights off, lights on. A two-slide carousel: the same scene in the dark, then glowing. Swiping becomes the reveal.
5. One big number for the offer. If there is a discount, let one number carry the design and keep everything else small. Three badges and five lines of text read as noise on a phone.
6. A Hindi headline with an English line under it. शुभ दीपावली or दीपावली की हार्दिक शुभकामनाएं set large, with your offer or message in English below. It feels local without losing readers who prefer English.
7. Dhanteras countdown stories. Three stories, one per day, with a countdown sticker and the same layout each time so they feel like a set.
8. A gift guide carousel. Group products by person (for parents, for your sister, for the office) rather than by price.
9. The behind-the-scenes post. Packing gift boxes, decorating the store, the team in festive clothes. Real photos often beat polished graphics this week.
10. A 3D product scene. Your product on a glowing plinth with diyas and soft bokeh. It is a strong ad creative because the product stays the hero.
11. A simple motion version. The same greeting with a flickering flame or lights turning on one by one, exported as a 6 to 10 second reel.
12. The quiet greeting. On Diwali itself, one clean design with your logo, a short wish and nothing to buy. It earns more goodwill than another sale post.

Setting Hindi text properly in festival designs

Nepali uses the same Devanagari script as Hindi, so this part of my work is everyday practice. Broken Hindi text is one of the most common problems in Diwali posts, and readers notice it.

• Use a font made for Devanagari. Google Fonts such as Mukta, Hind, Poppins and Noto Sans Devanagari support it. Latin-only fonts fall back to a random system font or show broken matras.
• Give the line more height. Devanagari matras sit above the top line (the shirorekha) and below the letters, and they get clipped when line height is tight. Add space and check the top and bottom of every line.
• Do not stretch or fake bold. Use the real bold weight of the font. Squashed or outlined Devanagari is hard to read at phone size.
• Type it, do not paste an image of text. Typed text stays sharp and is easy to fix when someone spots a spelling mistake.
• Get one native speaker to read it. A wrong matra in a festival greeting gets screenshots for the wrong reasons.

Sizes for every Diwali post and ad

Design the 4:5 version first, then rebuild it in 9:16 rather than stretching it. The layout usually needs to move, not just grow.

Diwali design mistakes to avoid

• Using the same free template thousands of other pages will post that morning
• Placing a discount badge over images of Lakshmi or Ganesha. Keep religious imagery respectful and keep offers separate
• Firecracker-heavy visuals. Many cities restrict firecrackers, and many audiences now prefer diyas and lights
• Too much text on ad creatives. One headline and one offer is enough
• Posting the greeting a day late, or forgetting to change your profile and story highlights back after the festival
• Leaving out Chhath when your customers are in Bihar, Jharkhand or eastern UP

Selling in Nepal as well? Plan Tihar in the same week

Brands that sell in both countries, or in the border towns between Bihar and eastern Nepal, can reuse most of the Diwali design system for Tihar. The lights theme carries over, Laxmi Puja falls in the same week, and Bhai Tika is Nepal's version of Bhai Dooj. Kukur Tihar, the day that honors dogs, is a gentle, very shareable post that Indian pages do not have. Check the Nepali calendar for the exact Tihar dates and write those posts in Nepali. My festival guide for Nepali business pages covers the full year.

Your Diwali design checklist

• Dates and posts planned from mid-October to Chhath
• One look for the whole series: your colors, fonts and layout
• The offer creative ready in 4:5 and 9:16 before you start any ads
• Hindi text set in a Devanagari font and checked by a native speaker
• A reel version of the greeting
• Someone ready to reply to comments and messages during the festival week

Diwali post design FAQs

When should brands start posting for Diwali 2026?

Start teasers in mid-October, about three weeks before Diwali on November 8, and launch the offer about two weeks out so ads have time to reach people before Dhanteras on November 6.

What size should a Diwali Instagram post be?

1080 x 1350 pixels (4:5) for the feed and 1080 x 1920 pixels (9:16) for stories and reels. Make both versions of any design you plan to run as an ad.

Should Diwali posts be in Hindi or English?

Write in the language your customers use. Many brands set the greeting in Hindi and the offer in English, which reads well for both groups. Use a proper Devanagari font for the Hindi.

If you want your Diwali posts, carousels and ad creatives designed in your brand style, I take graphic design projects from brands and agencies in India and Nepal, and briefs in Hindi are fine. You can also see my CV if you are hiring a designer for your team.
