Format guide • Personalized composition
Crop removes part of the image; extend adds content around the composition. For a personalized format, the first choice is suitable if the cut preserves the essential elements. The second can be studied when the decor lends itself to it, but constitutes an adaptation of the reference. Margins remain a third solution for preserving the entire image without pictorial addition.
Our oil offer: paint delivered rolled and its framing
Our oil paint is delivered rolled, without frame or frame. The painting estimate must therefore be distinguished from assembly and framing. Transmit the constraints of the frame or rebate before setting the necessary dimensions and reservations with the stakeholders concerned.
At Alpha Reproduction, we carry out your oil painting by hand to order, on quote, from €349, delivery included. Our offer includes 7 free edits. The final amount is confirmed by quote depending on the work, format, complexity and destination.
You receive photos of the paint for validation before shipment. The paint is delivered rolled, without frame or frame; assembly and framing are to be planned separately. For a personal project, send your reference and your brief to clarify the proposed achievement.

1. Measure the gap between the reference and the desired format
A landscape of 60 × 40 cm has a width/height ratio of 1.5. A format of 80 × 40 cm has a ratio of 2. Increasing only the width to fill this panorama would also widen the characters and objects.
To maintain proportions, you can adjust the image in the format or fill it with a cut. In this example, adjusting the entire image to 60 × 40 cm leaves 20 cm wide to be distributed into margins or added content. Filling 80 × 40 cm proportionally enlarges the image to approximately 80 × 53.33 cm before cutting 13.33 cm in height in total.
If the crop is centered, this represents approximately 6.67 cm removed at the top and bottom of this enlarged image. Positioning can be changed depending on the subject. These calculations describe geometry, not an automatic artistic proposition.
2. Crop when edges can be removed without imbalance
Crop can work if the scene has peripheral space and the important element remains readable. It can also reinforce a detail, provided that this change corresponds to the project.
Examine the cut across the entire image. A hand, secondary character, or horizon line can appear incidental in a miniature and become essential to reading. Signature and inscriptions must be taken into account.
| Image type | Point to check before cutting |
|---|---|
| Portrait | Face, hairstyle, hands and eye space |
| Landscape | Horizon, depth and elements at the ends |
| Architecture | Perspective and integrity of important structures |
| Group | Characters and relationships between gestures |
| Work with text | Complete registrations and readability |
For printing, a cut also reduces the portion of pixels retained. Check the useful resolution of this part in the final format, and not just that of the initial file.
3. Extend when the addition can remain consistent
A sky, a simple wall or an open landscape can offer possibilities for extension. However, it is necessary to maintain light, perspective, scale, texture and rhythm of shapes. Seemingly simple areas may require adjustments to keep the connections convincing.
Complex architecture, a drape or a group of characters are more difficult to extend without inventing significant elements. Feasibility must be assessed on the actual image; it cannot be guaranteed by the number of missing centimeters alone.
The extension can be digital, manual in a new painting, or combine a preparatory study and a painted interpretation. In any case, it constitutes an adaptation. There adobe Generative Extension Documentation presents content creation beyond the image: the result is not a discovery of the missing parts of the original.
If AI intervenes, check repeated patterns, inconsistent objects, perspective lines and connections. Do not present an invented addition as a certain historical reconstruction.

4. Margins: preserving the image without inventing a decor
An entire image can be placed on a wider support with a plain margin or in a suitable frame. The original drawing remains intact, while the presentation meets the requested exterior format.
For a work on paper, a mat can be part of the assembly. For a painted canvas, a presentation with visible margins or a specific frame must be studied according to the support; do not automatically transpose the same assembly.
| Solution | What she keeps | What she changes |
|---|---|---|
| Crop | Proportions of elements kept | Visible field and sometimes balance of the scene |
| Extension | Can preserve central image | Adds an interpretation around the reference |
| Margins | Whole image and proportions | Presentation and dimensions of the support |
| Different proportional format | Whole composition without addition | Dimensions initially envisaged |
A frame canvas reserve is not necessarily a decorative margin. Define the visible facade, edges and reserve on the back. Consult preparing a chassis image.
5. Validate the overall result before details
- Keep the initial reference and identify the suitable version.
- Indicate the width × height format and the ratio.
- Clearly show cut or added areas.
- Check composition, perspective and proportions.
- Control detail and sharpness at final scale.
- Have cost, corrections and scope of agreement confirmed.
Ask for a complete view, then useful details. A close-up does not show whether the composition remains balanced. A framing preview does not constitute a colorimetric validation of the final support.
Find out validations before a series of draws and color charter and proof.
6. Request an unambiguous custom format
Send the image, the desired format and the constraints of the location. Specify whether your priority is to keep the entire composition, fill in the frame or keep certain details. These objectives are not always compatible without compromise.
For Alpha Reproduction, transmit the project via the contact page. Specify the possible options, cost and schedule before ordering. Check the rights necessary to reproduce and adapt the reference.
This guide is for a new reproduction or file. Do not cut or fold an existing painting to fit a frame; have the assembly examined by a professional.
Give advice on choosing your painting
Explore famous paintings from the catalog, then open the works sheets that you like to compare the formats and presentations offered. For a constraint of dimensions, frame or composition, present your project to Alpha Reproduction in order to confirm the possibilities before ordering.
Frequently asked questions
Does cropping distort the image?
It removes part of the scene without stretching the preserved elements. However, it can change its balance.
Can any table be extended?
Feasibility depends on decor and complexity. Some additions would significantly modify the reference or require significant interpretation.
Does an AI extension reconstruct the original?
It produces new content and does not prove the appearance of missing or missing parts.
Are margins a solution without deformation?
Yes if the image is placed proportionally. They change the presentation and size of the support.
Does an extension always cost more?
The work and price depend on the image, process and planned validation. Ask for a quote rather than a supposed extra.
What to check for a religious painting?
Preserve essential gestures, attributes, characters and inscriptions, then validate any adaptation.
Should it be validated before production?
Yes. Confirm format, cut or add, edges, file version, and scope of the agreement before launch.
