थंबनेल पूर्वावलोकन परीक्षक
प्लेटफ़ॉर्म वास्तव में जिन आकारों में दिखाते हैं—फ़ीड, साइडबार और मोबाइल सर्च—उनमें थंबनेल का पूर्वावलोकन करें, ताकि जाँच सकें कि उसका टेक्स्ट पठनीय रहता है या नहीं।

Thumbnail Preview Tester
केवल फ्रंटएंड प्रीव्यू — कोई अपलोड या बाहरी सेवा नहीं।
Preview sizes
Rendered at 360x202, 168x94, and 106x60 — the four-word headline is legible at the first two and illegible at search size.
How the Thumbnail Preview Tester works
- Upload the thumbnail you are about to publish.
- Compare it at all three sizes, especially the smallest one.
- If the text fails at 106 px wide, cut words rather than shrinking the type further.
FAQ
How many words can a thumbnail carry?
Three or four at most, set very large. The smallest render is around a hundred pixels wide, and anything more becomes texture rather than text at that size.
Does the light or dark background matter?
Yes. A thumbnail with white edges dissolves into a light feed and floats oddly in a dark one. Check both, since viewers control the theme, not you.
Is my image uploaded?
No. It is rendered locally in the page for preview only.

Thumbnail Preview Tester exists because thumbnails are designed at full size and consumed at a hundred pixels — the small preview is the one that decides.
