The page editor is where you will design your layouts, using a range of tools and features: templates, candid images, text frames, shapes, elements, and backgrounds.
Opening a page in the editor
In the book manager, hover over a page to click on the Edit button. The page editor will launch.
Note: users with a role of Staffer may only open pages assigned to them in the editor. You can choose to highlight page owner status in the book manager tab to see what pages are available to edit under your login. Pages may not be available for editing if they have been submitted for review or approved by an Editor-in-Chief.
Important: Memento recommends using a three-button mouse for best results. Laptop users with tracker pads may find this feature hard to use. We strongly recommend using a mouse for best results in the editor.
Navigating the page editor
The page editor is organized into four areas:
| A- Left-side tabs to access content and book settings | B- Top menu for project status and view |
| C- Editor features to add empty frames and attributes | D- The canvas where your page is built |

| To move to the previous or next page in the book, click on the side arrows next to the canvas. | ![]() |
| To navigate to a different area of your book, click on the Pages tab in the bottom left corner. the section titles appear over the first page in the section. A preview of all the pages in your book will appear for you to scroll through. Click on a page preview to launch it in the editor. | ![]() |

Working with double-page spreads
The first and last pages of your book are, by default, a single page. All other pages in the book are presented as right- and left-facing pages. When a common background is applied to both pages or frames cross the gutter, a notification appears at the top of the canvas to indicate the pages are linked.
In the example below, a single image is used as the background, and a shape and photo cross the gutter.
If pages have been moved on the ladder resulting in a double-page spread becoming broken apart (eg. page inserted between a left- and right- side or an odd number of pages is created above the spread, converting the left page to right and the right page to left), then a warning will appear at the top of the page. Click the warning for more information, to learn how to resolve the issue or unlink the pages.

Zooming & Panning the Canvas
By default, the editor displays both the left and right side pages. For a more detailed view, use the zoom slider at the top of the editor. To recenter the page, hold the space bar, click down on the canvas and drag it into a new position.

Double-click the zoom slider to reset the canvas view to 100%, or move to the next page.
Interior Page Guidelines
Interior page dimensions (length, width) are automatically preset based on the book type assigned by your studio. Pages are surrounded by guidelines in the editor. These lines are used to assist you in placing your page content to achieve best possible results when your book is printed.
A- Red trim guidelines indicate the area of the canvas that will be cut off after the book is printed and bound. This is called the bleed area. Be sure that all backgrounds, banners or images that deliberately spill off the page edge extend over this area to the edge of the page. This ensures a clean finish to your book.
B- The gutter is the area between facing pages. Content too close to the gutter may be caught in the folds of the pages. Keep this in mind when editing across a double-page spread.
C- Gray shading defines the page margins, also known as the safe margins. Keep all text and people's faces out of this area to ensure that nothing important gets too close to your page edges.

Cover Guidelines
Covers dimensions are also preset by the book type assigned by your studio. Your book may be set up with a hard cover, a perfect bound soft cover and/or a saddle stitch cover, depending on the options offered by your studio..
Red spine guidelines are in the middle of the cover page. The more pages in your book, the larger the spine. Should you wish to add spine text, keep it small and positioned within the middle of the spine guidelines. Ask your publisher if there are any limitations for spine text (e.g. not available on saddle stitch books or under a particular page count
Grey safe margins are displayed around the edge of the cover page. An additional green margin flanks the spine guidelines. Keep all text, photos of faces and important feature images within the safe margins.
A red trim area surrounds the cover page. Soft cover books will show a thin red trim line, since these are simply trimmed like an interior page. Hard cover books may show a much wider red area, representing the part of the cover that wraps behind the hardback board of the cover. Be sure to extend backgrounds and banners into this area to achieve a clean continuous look to your book.
