Instagram Reels orientation should always be vertical, 9:16 — filling the whole phone screen with no black bars down the sides or across the top. Diya makes every video in 9:16 automatically, so there's no orientation to choose and nothing to get wrong before you even start.

Why is 9:16 the best shape for Instagram Reels?

Instagram shows Reels full-screen on a phone, one after another, as people scroll. If your clip isn't already vertical, Instagram has to crop it or add bars to force it into that frame — and Instagram decides what gets cut off, not you.

That usually shows up in the worst places: a face sliding half out of frame, or a wish you typed carefully landing right at the cut edge once it's squeezed into a vertical feed. When a video is already built in 9:16 from the start, your photos, your wish and any name art stay exactly where you placed them. Nothing gets re-cropped after the fact, because nothing ever had to change shape in the first place.

This matters even more once you add a wish or a name on screen. A caption placed near the edge of a video that starts in the wrong shape can end up half-cropped the moment Instagram forces it into the vertical feed — getting the orientation right from the very start saves you from redoing the whole layout later.

Do Reels, WhatsApp Status and YouTube Shorts use the same shape?

Yes — Instagram Reels, a WhatsApp Status video and a YouTube Shorts video are all built for the same full-screen phone frame, so a single 9:16 file works across all three without re-editing anything.

So whether you're sending a Diwali wish, a birthday clip or a short wedding invitation teaser, one 9:16 video made in Diya can go straight to your Reel and your WhatsApp Status on the same day, without touching it again in between. That matters most right before a festival or a wedding, when you want to send one video everywhere at once — your family group on WhatsApp Status first, then as a Reel a little later, with no re-cropping in between.

How do you make a 9:16 video with Diya?

You never pick a shape inside Diya — every template, from festival wishes to wedding invitations, is already built as a vertical 9:16 video, so all you choose is the template, the photos and the words.

1. Open Diya and pick a template — festival, birthday, anniversary, love, devotional or wedding invitation
2. Add your photos from the gallery, in the order you want them to play
3. Type your wish or a name — Diya can turn a typed name into glowing name art
4. Pick music from Diya's free music library, or use your own song from your phone, with beat-sync lining up the photo changes to the beat
5. Save the video and share it straight to WhatsApp Status, or post it as your Reel

The whole video comes together on your phone in about 3 minutes, and your photos are never uploaded anywhere — everything happens on the device in your hand, with no account needed to get started. If you'd rather begin from a pile of photos and a song idea before settling on a template, this guide on making a video from photos with music covers that side of it in more detail. And if your photos are sitting in your Android gallery and you're not sure where to begin, turning photos into a video on Android walks through the basics.

What if your photos aren't already vertical?

This is the part that trips up most people. A landscape photo dropped into a vertical frame has to go somewhere — either it gets zoomed in so it fills the height, or it sits centred with some soft fill showing on the sides.

A close, personal photo — a face, a plate of mithai, a single diya — usually looks fine zoomed in, since there's nothing important near the edges to lose. A wide photo, like a whole family lined up or a hall decorated for a sangeet, usually looks better centred, so you don't crop out the people standing at the sides. Try your first photo both ways in your head before you lock in a full set of photos for the video — it's usually obvious right away which treatment the rest of your photos need too. If you can't decide, centring is the safer default for group photos, since nobody's face gets cut by a zoom that goes too far.

What does Diya's free plan include, and what does Premium add?

Your first 2 videos in Diya are free, and after that you get 1 free video every day — all of it already in the right shape for Reels, with no orientation decisions left for you to make.

Free videos export in 720p and carry a small "Diya" mark along with a short "Made with Diya" end card. Premium — Lifetime, Monthly or Annual — removes both of those and unlocks 1080p, with 4K available on Android, plus premium templates. There are no ads either way, on Free or on Premium.

• Free: first 2 videos free, then 1 free video a day, 720p, a small "Diya" mark and end card
• Premium: Lifetime, Monthly or Annual — removes the mark and end card, adds 1080p and 4K on Android, plus premium templates

Diya also keeps a festival calendar that reminds you before the day itself arrives, so you're not scrambling to make your Diwali or Bhai Dooj video at the last minute. The app runs in 11 languages, so you can write your wish the way your family actually speaks at home. For a wedding, you can add an RSVP link to the invitation so guests can reply straight from the video you send them.
