Measured from the platform's own overlay, or labeled as a guide
X (Twitter) safe zone
Short answer
The X help page Koldflux could reach returned a 403 and gave no margins, and the recorded device and hub figures differ. This page offers a conservative envelope for a vertical post rather than presenting one figure as X's own.
Key takeaways
- The X help page Koldflux reached on 2026-10-03 returned a 403, so no X figure was available to quote.
- The recorded device and hub sources disagree, so this page shows the range and an envelope.
- The bottom is where they disagree most: one recorded source says 22% and the other says 6%, and the envelope takes the larger.
- It is for a vertical 9:16 post; a 16:9 in-feed image is a different frame.
The overlay
One surface, and X gave no geometry to Koldflux. The overlay is an envelope from the recorded figures.
Sources disagree · Media Studio FAQs (X Help) · Last checked 2026-10-03
Recorded values range from 4-6% at the top, 6-22% at the bottom, 0-4% on the left and 0-4% on the right. The overlay is an editing guide, not a platform value.
Sources disagree on these margins, so Koldflux does not publish one platform value. The overlay is a cautious editing guide, not an official number.
Surfaces on this platform
One surface, in conflict: the recorded device figures and the recorded hub figures disagree, and the table below shows the gap on each edge. The overlay takes the larger.

CONFLICT · The recorded sources disagree on x post, so the range is shown below and the download is a conservative envelope.
- Top
- 6% · 115 px
- Bottom
- 22% · 422 px
- Left
- 4% · 43 px
- Right
- 4% · 43 px
| Reported | Top | Bottom | Left | Right |
|---|---|---|---|---|
| Smallest reported | 4% (77 px) | 6% (115 px) | 0% (0 px) | 0% (0 px) |
| Largest reported | 6% (115 px) | 22% (422 px) | 4% (43 px) | 4% (43 px) |
The overlay below uses the largest figure on each edge, so a design inside it is safe under every figure on record. It is an editing guide, not a platform rule.

What the X pages gave us, and what they did not
The X Media Studio FAQ page Koldflux referenced returned a 403 on 2026-10-03 and gave no safe-zone geometry. No X figure is quoted on this page, because none was read.
The two figures on record therefore both come from measurement rather than from X, and they disagree badly at the bottom. One records 6% at the top, 22% at the bottom and nothing at the sides. The other records 4% at the top, 6% at the bottom and 4% on each side.
That is a sixteen point spread at the bottom, which is 115 px against 307 px at 1080 x 1920. A design that clears 307 px is safe under both readings. A design that clears 130 px is safe under only one, and this page cannot tell you which reading is right, so the overlay takes the larger.
The disagreement at the top is much smaller, 6% against 4%, which is 115 px against 77 px. Where sources disagree a little, the practical cost of choosing the larger is low, and this page takes the larger on every edge rather than picking per edge.
A vertical post is one of several frames
X posts at several aspect ratios and the interface differs by ratio and by client. A 9:16 vertical post carries the most interface and so needs the largest reserve; a 16:9 in-feed image sits in a much shorter frame and the same percentage describes a smaller area.
This page is for the vertical post. At 1080 x 1920 the envelope takes 115 px off the top, 422 px off the bottom and 43 px off each side, leaving a rectangle 994 px wide and 1,383 px tall.
For a 16:9 post, the link-preview and image-size pages cover the frame and the published link-card figures. Those are a different object at a different ratio, and the vertical envelope will not describe it.
| Edge | Margin | Working | Pixels |
|---|---|---|---|
| Top | 6% | 1920 x 0.06 | 115.2, shown as 115 |
| Bottom | 22% | 1920 x 0.22 | 422.4, shown as 422 |
| Left | 4% | 1080 x 0.04 | 43.2, shown as 43 |
| Right | 4% | 1080 x 0.04 | 43.2, shown as 43 |
| Safe width | 92% | 1080 x 0.92 | 993.6, shown as 994 |
| Safe height | 72% | 1920 x 0.72 | 1,382.4, shown as 1,382 |
Computed from the 1080 x 1920 frame and the recorded margins.
The safe height in the table is the percentage before the rounded pixel margins are subtracted. Subtracting the drawn values gives 1920 less 115 less 422, which is 1,383, one pixel more than the rounded percentage suggests. The overlay draws the pixels, so 1,383 px is what it actually clears.
What to do on X when there is nothing to check against
With no geometry in the X pages Koldflux reached on 2026-10-03, the overlay is a floor rather than a boundary, and the value of it is that it forces the layout decision early rather than after the post is up.
Three things are worth doing that the overlay cannot do for you. Check a draft in the client you actually post from, because the reply and action column sits where the client puts it. Keep the subject inside the top half rather than the top 6%, since the recorded sources disagree about how much room the bottom really needs. And keep a copy of the frame, because a re-crop between clients is not visible in the file you uploaded.
None of those three is derived from a figure on this page, and this page does not present them as if it were.

This is a conservative envelope, not an official specification. The X help page Koldflux reached on 2026-10-03 returned a 403 and carried no safe-zone geometry, so this is a conservative envelope, not an X rule: it takes the larger of the two recorded margins on each edge, so a design inside it survives whichever source is right. The file says so on its face.
Frequently asked questions
What is the X post safe zone?
No X figure was found. The X help page Koldflux reached on 2026-10-03 returned a 403, so the overlay on this page is an envelope built from two recorded sources that disagree, labeled as not an official specification.
Why is the bottom margin so large on X?
Because the two recorded sources disagree most at the bottom, 22% against 6%, and the envelope takes the larger. At 1080 x 1920 that is 422 px rather than the 115 px the top takes.
Does this overlay work for a 16:9 X post?
No. It is drawn for 1080 x 1920. A 16:9 in-feed image is a different frame, and the link-preview and image-size pages cover that object.
Is the X safe zone the same as the Threads one?
No. The recorded Threads envelope takes 18% off the bottom and this one takes 22%, and they come from different recorded sources. Use the one for the platform you are posting to.
